4 DPO: Can Implantation Occur Four Days Past Ovulation?



What can I expect at 4 days past ovulation?

At 4 dpo, you are in the middle of the luteal phase of your menstrual cycle.

The luteal phase is the phase between ovulation and your next expected menstrual period. In the luteal phase, the levels of your estrogen and progesterone are high because they are preparing your uterine lining for possible pregnancy that might happen every month, as your body does not know if you are actively trying to conceive or not.

If you do not conceive, the uterine lining is going to be shed, and it is going to disappear with your next menstrual flow.

What happens with the egg 4 days past ovulation?

When you are ovulating, one of your ovaries is going to release an egg that begins traveling into your fallopian tube. If the sperm is present in your body at the time that the egg is released, the egg and sperm are going to join their forces and create a fertilized egg, or a zygote, as we call it.

On day four past ovulation, the zygote is going to be somewhere on the way to your fallopian tube. The goal of the fertilized egg is to implant itself in the lining of your uterus and begin the long journey to pregnancy.

How many DPO implantation can happen?

In the majority of cases, implantation is likely to happen somewhere between six and twelve days post population, even more likely somewhere in the window between days eight and ten.

However, not every implantation is successful; this process is rather complicated, and 10 to 40% of fertilized eggs are unable to implant. Very early pregnancy loss is also common at this stage of the journey.

And yes, it is way too early to take a home pregnancy test 4 days past ovulation.

Can implantation occur 4 days after ovulation?

Unfortunately, implantation is not very likely to happen 4 DPO. If you happen to notice any bleeding or even spotting around 4 DPO, your best and safest bet is checking in with your healthcare provider, as this time is way too early for implantation bleeding.

Can I take a pregnancy test 4 DPO?

Home pregnancy tests work by detecting a high level of a hormone called hCG, which is released once the implantation has been detected by your body.

At four days post ovulation, it might be a bit too early for implantation to even take place, which means that it is not likely to take an accurate positive result, even if fertilization has been successful in the first place.

Even though you probably do not want to hear this, the best possible option is to stick it out and wait until the week after your first missed period before you decide to take the test. In the circles of women who are trying to conceive and sharing their stories, the two week wait can feel notoriously long.

Even though this wait is agonizing, it is a necessary part of the pregnancy journey, and you just have to wait it out; there is no shortcut.

Early pregnancy symptoms and 4 DPO symptoms

At 4 DPO, it is probably too for any pregnancy symptoms to start appearing. However, as time passes and as things progress, there are some early pregnancy symptoms to look out for, and it is helpful for you to get familiar with all of those pregnancy symptoms earlier than later.

It is also beneficial to get familiar with the pregnancy symptoms that you will need to start tracking in the weeks to come to help document your journey, as well as provide the full picture of it to your gynecologist.

The earliest symptoms of early pregnancy that you might start to notice can include:


Some women may start to experience mild cramping around day four post-ovulation, but it is more likely that you will need to wait a few weeks for this symptom to appear and actually mean pregnancy.

If you start feeling some light cramping in your pelvic and abdominal around days ten to fourteen, it could be a sign that implantation is taking place. However, this light pelvic or abdominal cramping can also be a sign that you may be starting your menstrual period.

There is really no way to know, aside from waiting it out and taking the home pregnancy test.


Some light spotting in the two-week wait can be a sign of implantation bleeding, which typically happens around days 6 to 12 after the egg has been fertilized, as the egg needs some time to travel down to the uterus and get itself implanted there.

As we previously mentioned, if you begin spotting at 4 DPO, you may want to seek advice and medical expertise from your doctor since it is not likely caused by implantation bleeding.

Nausea and vomiting

Nausea and vomiting are among the most common signs of early pregnancy, as they are caused by rising hormone levels. However, it might just be way too early to experience nausea and vomiting at 4 DPO.

Tender breasts and nipples

Your nipples and your breasts can also become sensitive due to hormonal changes that your body is going through during early pregnancy. However, just like with cramping, sensitive breast and nipples could also be a sign that you may be starting your menstrual period, as they are common symptoms of PMS.

Other common symptoms of early pregnancy can also include:

  • Fatigue
  • Darker, larger areolas and tingling nipples
  • Light cramps or implantation cramping
  • Nausea and vomiting
  • Food aversions
  • Food cravings

The above-mentioned symptoms can start appearing in the next few days or only in the next few weeks, but they might not appear at all. Do not be alarmed by this; every woman is different, and every pregnancy is unique, there is no rulebook for this.

There is no definitive sign or a reliable sign that will let you know if you are pregnant at a very early stage. The only reliable way is to take a pregnancy test that will measure your pregnancy hormones and hormone hcG when the time is right.

Do not take any pregnancy tests before your two-week time frame expires (as it can result in false positives), relax, let nature do its job, and hope for a positive pregnancy test once the time is right.
