But what is ovulation bleeding and why does it happen? In this MomJunction post, we answer these questions and more about ovulation bleeding.


Is Bleeding Or Spotting During Ovulation Normal?

Yes, spotting or bleeding during ovulation is quite normal for some women. It can happen at different times during the cycle and due to varying reasons. There is no sure way to know if what you are experiencing is menstrual spotting or implantation bleeding.

Possible Causes Of Bleeding During Ovulation

Although there could be many probable causes for ovulation bleeding, there are two known reasons that certainly result in bleeding or spotting during ovulation (2):

A drop in the estrogen levels during ovulation makes the uterine lining to decrease in thickness and shed the tissue. This could result in bleeding from the uterus around the time of ovulation.

When the egg is released, the ovaries rupture and bleed, letting the blood pass through the follicle tubes.

What Does Ovulation Bleeding Look Like?

Ovulation bleeding is lesser than menstrual bleeding, and it is either light pink or dark brownish red. It accompanies cervical mucus and mild menstrual-like pain.

Is Ovulation Bleeding Or Spotting A Sign Of Fertility?

Though ovulation bleeding or spotting is a positive sign, not every woman experiences it, and therefore cannot be a reliable sign of fertility. Understanding your ovulation by tracking the dates or using ovulation predictor tests is a better way to know. Indulging in sex when you are closer to ovulation will increase your chances of conception.

When Does Ovulation Spotting Occur?

Ovulation spotting usually occurs before, after or during ovulation, which is anytime between 11 and 21 days after the first day of your last period. It might also happen sooner or later depending on the length of the menstrual cycle (3).

Other Signs And Symptoms Of Ovulation

Ovulation spotting may or may not occur, but the other associated symptoms include (4):

  • Increased cervical fluid that looks similar to egg white
  • Cervical changes especially its position and firmness
  • Changes in basal temperature of the body
  • Dull pain at one side of the abdomen
  • Increased libido
  • Breast tenderness
  • Higher levels of luteinizing hormones measured with ovulation test
  • Bloating
  • A heightened sense of smell, taste, and vision

If you see these signs, know that you could be ovulating and that it is the right time to try to conceive.

If bleeding or spotting is the only symptom you notice, then you may not know whether it is ovulation spotting or implantation spotting or menstrual period. Knowing the difference helps.

Ovulation Bleeding And Pregnancy – How Are They Related?

Since ovulation bleeding indicates fertility, it is the right time to try and conceive. Getting a confirmation from the doctor that mid-cycle bleeding is not a complication, and is a sign of ovulation could help you determine the right time to have sex, to increase the chances of pregnancy.

When Should You Take A Pregnancy Test?

You may take a home pregnancy test around a week after you miss your period. This would be around 20 days after ovulation bleeding.

A pregnancy test detects the amount of hCG (human chorionic gonadotropin) in urine. The hormonal levels are too low early in pregnancy, but they rise quickly eventually. Therefore, taking the test too soon can result in a false-negative. If the test results appear favorable, consider an appointment with your doctor to confirm your pregnancy.

Next, we answer a few commonly asked queries on ovulation bleeding.

Frequently Asked Questions

1. How long should ovulation bleeding last?

Ovulation bleeding usually lasts for a few hours to a day, but in some women, it may extend to two or three days (8).

2. Does ovulation bleeding mean you are pregnant?

Ovulation bleeding in the middle of the menstrual cycle does not mean you are pregnant. It means you are fertile. And that increases your chances of getting pregnant.

3. What if you experience severe bleeding while ovulating?

Severe bleeding and pain for more than one cycle could indicate a complication such as endometriosis, irritable cervix, or polyps in the uterus. Doctor consultation and follow-up tests will help in getting the right diagnosis.

4. Can brown spotting during ovulation indicate the right time for conception?

Brown spotting during ovulation is an ideal time for you to conceive (4). But, if you also have any vaginal irritation along with brown spotting, it could suggest a pathological issue.

If you experience regular bleeding or abnormally heavy bleeding between your periods, you should consult your healthcare provider. The timely diagnosis helps you understand why it is happening and lets you take the necessary steps to manage the potential cause.
