What’s Implantation Symptoms

While many women feel no signs of implantation, some women do notice signs and symptoms that implantation has occurred. Signs may include light bleeding, cramping, nausea, bloating, sore breasts, headaches, mood swings, and possibly a change in basal body temperature.

About one-third of all women experience implantation symptoms after they get pregnant. Implantation happens when a fertilized egg attaches to the lining of the uterus. Some women do notice signs and symptoms that implantation has occurred. But — and here’s the frustrating part — many of these signs are very similar to PMS

Implantation is the process by which a fertilized egg attaches itself to the lining of the uterus, and it occurs six to twelve days after fertilization. While in some very early pregnancy cases women do notice signs and symptoms that implantation has occurred, often no symptoms are noticed at all as they occur so early

For some women, they notice signs and symptoms that implantation has occurred. The important thing is to know what’s happening with your own body.

Most women don’t notice signs of implantation at all. While implantation cramping and light spotting may occur, some women don’t ever experience these symptoms at all. If you do have cramping or spotting, it doesn’t mean that you’re definitely pregnant—it’s also a common sign of PMS. (If your period does arrive, you can be sure that’s not implantation bleeding.)

Implantation occurs in a secret window of time called the fertility window. The exact timing of this window is difficult to pinpoint, which is why pregnant women may notice signs of implantation but mistake them as an early PMS or ovulation symptom because they didn’t know they were trying to get pregnant. It’s important to track your cycle closely and understand when you are at your most fertile.

We don’t know if we should blame Hollywood or the false reality of social media, but the phrase “getting pregnant” gets tossed around as if it’s a simple one-step process. But there are actually a ton of tiny, amazing things that need to happen in your body to result in pregnancy.

After the sperm and the egg join (conception), the combined cells start multiplying pretty quickly and moving through one of your fallopian tubes to your uterus. This cluster of rapidly growing cells is called a blastocyst.

Once in your uterus, this little bundle of cells has to attach, or implant, into your uterine wall. This step — known as implantation — triggers rising levels of all those fun pregnancy hormones (estrogen, progesterone, and hCG, or human chorionic gonadotropin).

If implantation doesn’t happen, your uterine lining is shed in your normal monthly period — a serious disappointment if you’re trying to get pregnant, but a reminder that your body is likely prepping for you to try again.

But if implantation does occur, your hormones — sometimes a nuisance, but doing their job — cause the placenta and the embryo (your future baby) to develop and your uterine lining to stay in place and support your pregnancy.

Implantation takes place anywhere between 6 and 12 days after you ovulate. It most commonly occurs 8 to 9 days after conception. So the exact date of implantation can depend on when you ovulated, and whether conception occurred early or late in the ovulation window.

When you’re hoping to get pregnant, it’s natural to be very aware of your body and notice every change, no matter how small.

Assuming a lack of symptoms means you’re not pregnant? Not so fast. Keep in mind that most women experience no signs at all of conception or implantation — and are still pregnant! — though some women do experience signs of implantation.

Let’s explore some symptoms you might notice if implantation has occurred, but keep our little disclaimer in mind:

Having the symptoms listed below doesn’t necessarily mean you’re pregnant — and having no symptoms doesn’t necessarily mean you’re not.

Can you experience pregnancy symptoms at 5 DPO?

Javier Díez/Stocksy

Women who are trying to conceive are often particularly sensitive to what is happening with their bodies as they are looking for symptoms of pregnancy.

Some women share anecdotes about their pregnancy symptoms as early as 4–5 DPO, while others report not noticing any changes to their body until much later.

Although signs are possible this early on, they are unlikely to appear this soon in the majority of people. Many of the early symptoms, such as breast tenderness or fatigue, are instead linked to hormonal changes during ovulation or menstruation.

Implantation may already have taken place at 5 DPO, or it may be about to happen soon. As a result, depending on the time of conception, it is possible for women to feel some symptoms of pregnancy this early on.

Pregnancy tests are not accurate at 5 DPO, but some women later find that their early symptoms were indeed due to pregnancy.https://712b276822da0e180549b09b83245c68.safeframe.googlesyndication.com/safeframe/1-0-38/html/container.html

What is happening in the womb at 5 DPO?

At 5 DPO, if the sperm has reached and fertilized the egg, the cells within the newly formed zygote begin multiplying to create a lump of cells called a blastocyst.

These cells continue to multiply as the blastocyst makes its way down the fallopian tubes and into the uterus.

When the blastocyst reaches the uterine wall, it attaches itself to get access to nutrients through the blood. At 5 DPO, the blastocyst may either be traveling to the uterine wall or already connected to it.

If it is attached, the blastocyst has started its journey toward becoming a fetus, and pregnancy is underway.HEALTHLINE NEWSLETTERGet actionable tips to help support your parenthood journey

Earliest signs of pregnancy

The specific symptoms of pregnancy vary hugely from woman to woman. There is no “normal,” as each pregnancy is unique.

However, some of the earliest symptoms that women may notice tend to include the following:

Implantation cramping and bleeding

Women may experience cramps very early on in pregnancy. These are due to implantation, which is when the fertilized egg attaches to the lining of the uterus.

Implantation cramps may occur a few days after ovulation, and many women say that they feel cramps around 5 DPO. These cramps may occur in the lower back, abdomen, or pelvis.

Around 25 percentTrusted Source of women may notice slight bleeding around the time of implantation. This is called implantation bleeding, and it tends to be lighter in color and flow than a menstrual bleed.

Raised basal body temperature

Many women keep track of their basal, or baseline, body temperature while trying to conceive because it changes throughout the menstrual cycle. The temperature increases after ovulation and may stay higher than usual until the period begins.

A basal body temperature that remains unusually high beyond the typical length of time may indicate pregnancy.

However, these signs are not unique to pregnancy and can be due to another hormonal or lifestyle factor.

Other early signs and when they happen

According to the National Institutes of HealthTrusted Source, other early signs and symptoms of pregnancy may include:

  • Breast tenderness. Hormone fluctuations may cause the breasts to swell, feel tender, and tingle or itch. Women may notice these symptoms as early as 1–2 weeks after conception.
  • Fatigue. Changes in hormones, especially a steep rise in progesterone during the early stages of pregnancy, may make women feel sleepy throughout much of the day. Fatigue can occur as soon as 1 week after conception.
  • Headaches. Raised hormone levels may also trigger headaches early on in a pregnancy, although the stage at which they appear can vary.
  • Food cravings. Many women find that they have very specific cravings during pregnancy, and these often begin early on.
  • Food aversion. Just as women may crave particular tastes, they can begin to find other flavors repellant. The smell or taste of some foods may make them lose their appetite or feel nauseous.
  • Urinating more frequently. The need to urinate more often is a sign of pregnancy in some women. It may be due to the increased levels of pregnancy hormones in the body, which increase blood flow in the kidneys and pelvic region.
  • Mood swings. Significant mood swings may also be an early sign of pregnancy. Again, these can result from significant changes in hormone levels. Mood swings may begin a few weeks after conception.
  • Morning sickness. Women may experience nausea and vomiting at any time throughout the day and as early as 2 weeks after conception.

Some women also report feeling dizzy or wobbly early on in pregnancy, often when they get up after lying down. This symptom may be due to changes in the blood vessels carrying oxygen to the brain.

Some women cannot explain any specific symptoms or changes in their body, but they intuitively feel that something is different.

They might describe it as not feeling like themselves or feeling as though they are suddenly always a step behind. This may be a sign of fatigue and an indication of hormonal changes.

When can you accurately test for pregnancy?

As tempting as it can be to take pregnancy tests early and often, it may not be helpful. At 5 DPO, there is no reliably accurate way to check for pregnancy.

Most tests check for a hormone called human chorionic gonadotropin (hCG), which the placenta makes. This hormone starts building up in the body after implantation.

While implantation may occur early on in some women’s menstrual cycles, it does take time for the hormone to build up to a level in the blood that will make it detectable in a blood or urine test.

According to the American Pregnancy Association, blood tests for hCG levels should be accurate 11 days after conception, while it would be best to wait 12–14 days before taking a urine test.

Taking a pregnancy test too early may give inaccurate results. It is possible that a pregnant woman could still get a negative result if the level of hCG has not yet built up in her body.

A false positive is also possible, which is a positive result on a pregnancy test when the woman is not pregnant. This can happen when a woman performs the test incorrectly, has a chemical pregnancy, or is taking certain hormonal medications as part of fertility treatment.


When a woman thinks that she might be pregnant, she may wish to note any signs and symptoms and discuss them with a doctor. It will only be a few more days until the level of the pregnancy hormone hCG in the blood or urine is sufficient to allow an accurate reading on a pregnancy test.

Pregnancy tests are available for purchase online.

Pregnancy Symptoms After Ovulation Day By Day

A pregnancy test can detect pregnancy before a woman misses her period, but some may notice symptoms even earlier than this.

The first sign of pregnancy is often a missed period, which happens around 15 days past ovulation (DPO). Some women may notice symptoms as early as 5 DPO, although they won’t know for certain that they are pregnant until much later.

Early signs and symptoms include implantation bleeding or cramps, which can occur 5–6 days after the sperm fertilizes the egg. Other early symptoms include breast tenderness and mood changes.

In this article, we look at the early signs and symptoms of pregnancy and discuss how soon women can get an accurate reading from a pregnancy test.

Possible signs of implantation


It’s actually a little unclear how common implantation bleeding is. Some sources claim that one-third of all women who become pregnant experience implantation bleeding, but this actually isn’t backed by peer-reviewed research. (Something on the internet that may not be true? Say it ain’t so!)

Here’s what we can tell you. Up to 25 percent of women experience bleeding or spotting in the first trimester — and implantation is one cause of first trimester bleeding.

This bleeding can be confusing, because it may happen around the time that your regular period would start. Most commonly though, it will occur a few days to a week before you expect your menstrual period.

There are other differences that can help you determine whether you are experiencing implantation bleeding or your period:

  • implantation bleeding is most likely to be light pink or brown (as opposed to the bright or dark red of your period)
  • implantation bleeding is more like spotting than an actual flow of blood

This spotting may occur once, or last for a few hours, or even up to three days. You may notice some pink or brown discharge when you wipe or on your underwear, but you won’t need a full pad or tampon — possibly not for many months!


It’s no secret that early pregnancy causes a rapid shift of hormones. More specifically, implantation is a trigger for the hormone surge — that’s why you can’t get that second pink line on a home pregnancy test until after implantation.

And the changing hormonal tide can also cause cramping. Furthermore, there’s a lot going on in your uterus as the fertilized egg implants and begins to grow.

While there’s no research indicating that implantation itself causes cramps, some women do feel abdominal tenderness, lower back pain, or cramping around the time of implantation. This may seem like a mild version of how you feel before your period starts.


Let’s talk about what’s going on down there.

If you’ve been monitoring your cervical mucus, good work, future mama! Being aware of what’s going on with your body can be empowering when trying to conceive.

You may notice some cervical mucus changes around the time of implantation.

During ovulation, your cervical mucus will be clear, stretchy, and slippery (sort of like egg whites). You probably already know this as your green light to get your baby dance on.

After implantation occurs, your mucus might have a thicker, “gummier” texture and be clear or white in color.

And in the days of early pregnancy, rising progesterone and estrogen may cause your mucus to become even thicker, more profuse, and white or yellow in color.

We hate to say it, though: Cervical mucus can be affected by a number of things (hormones, stress, intercourse, pregnancy, implantation bleeding or your period, etc.) and may not be a reliable indicator of whether or not implantation has occurred.

Start tracking your cervical mucus while you’re not pregnant, and a more useful indicator may be how different it is from your norm during each stage of your cycle.


Rising progesterone (which happens in early pregnancy) slows your digestive system down. This can make you feel bloated. But as so many of us know, this feeling can be a really common symptom of your period, too. Want to know why? Progesterone also rises when your period is imminent. Thanks, hormones.

Tender breasts

After implantation, levels of hCG, estrogen, and progesterone all increase rapidly. This can cause your boobs to feel very sore. (These hormones sure are multitaskers!) While many women experience breast swelling or tenderness before their periods, this is likely to be more noticeable than usual in very early pregnancy.


Ah, arguably the most famous of the early pregnancy symptoms: nausea, aka “morning sickness” (though it can happen at any time of day).

Increased levels of progesterone following implantation can make you feel nauseous. But again, this most commonly occurs around 4 or 5 weeks of pregnancy (about the time you miss your period).

Progesterone slows down your digestion, which can contribute to nausea. Rising hCG levels and a more sensitive sense of smell can make the problem worse — so now might be a good time to avoid cooking liver and onions.


While they’re good and necessary for a successful pregnancy, those wildly rising hormone levels (particularly progesterone) can also give you headaches following implantation.

Mood swings

Find yourself content and happy one minute, and weeping at a commercial on TV the next? Or excited to see your partner in the evening and then biting their head off over nothing? You may be experiencing mood swings.

Estrogen and progesterone, as well as hCG, increase very quickly following implantation. This can make you feel “off” or moodier than usual.

Implantation dip

While this sounds like some kind of weird appetizer, “implantation dip” refers to a one-day decrease in your basal body temperature that can occur as a result of implantation.

If you’ve been tracking your basal body temperature (BBT) to help identify your most fertile days, you likely already have a log of your daily BBT over the course of a few months.

Typically, a woman’s temperature is lower before ovulation, and then increases, and then drops again before her period starts. If you get pregnant, your temperature remains elevated.

Simple, right? Except there’s something else.

Some women seem to experience a one-day drop in temperature around the time of implantation. This is different than the drop in temperature that means your period is coming — in the case of an imminent period, your temperature would stay low.

In the case of implantation dip, your temp drops for one day and then goes back up. It’s thought that this might be due to a rise in estrogen, but it’s not entirely understood.

According to an analysis of more than 100,000 BBT charts from the popular app Fertility Friend, 75 percent of pregnant women using the app did not experience an implantation dip. Additionally, a dip was noted on approximately 11 percent of the charts of women who were not pregnant.

But it’s pretty interesting that 23 percent of app users who turned out to be pregnant did have a so-called implantation dip.

This isn’t a peer-reviewed, medically conducted study. (We wish it were — when will researchers get on this?) But it may be helpful when it comes to interpreting your BBT chart. An implantation dip is more likely if you’re pregnant than if you’re not, but you can absolutely still be pregnant without a dip.

The takeaway 

Trying to get pregnant can be both an exciting and nerve-wracking time. The days and months of your cycle can feel like forever when you’re waiting for a baby, and it’s easy to notice every tiny change in your body and wonder if it means you’re pregnant. This isn’t bad — knowledge is empowering — and in fact, it’s a very normal thing to do.

Some women do notice signs and symptoms that implantation has occurred. Signs may include light bleeding, cramping, nausea, bloating, sore breasts, headaches, mood swings, and possibly a change in basal body temperature.

But — and here’s the frustrating part — many of these signs are very similar to PMS. Additionally, most women experience no signs of implantation at all and are in fact pregnant.

The best way to know for sure if you’re pregnant is to take an at-home pregnancy test or call your doctor. (Keep in mind that even if you have implantation symptoms, it takes a few days for enough hCG to build up to turn a test positive.)https://www.myfinance.com/r/7ee2b3c3-dbef-4492-b8b1-7edacb8adf90?utm_campaign=hl-pregnancy&utm_medium=embed&selector=%23__next+%3E+div%3Anth-of-type%282%29+%3E+div%3Anth-of-type%283%29+%3E+div+%3E+div+%3E+div%3Anth-of-type%281%29+%3E+article+%3E+div%3Anth-of-type%283%29+%3E+div+%3E+div&cxsid=bac70fbf-6771-464b-b244-6dfca046d598&imre=aHR0cHM6Ly93d3cuaGVhbHRobGluZS5jb20vaGVhbHRoL2ltcGxhbnRhdGlvbi1zaWducw%3D%3D&_mfuuid_=d1cff6a4-d42b-4287-92f4-e6331e81d670&width=750

The “two week wait” — the time between ovulation and when you can usually get a positive pregnancy test — can test all your patience. Keep paying attention to you and your body, find some activities you particularly enjoy to take your mind off the wait, and know that you’re going to be an amazing parent.
