Question: What causes light or heavy spotting after ovulation? Is it normal or due to pregnancy?

Whether you are spotting just after the end of your period or anytime within your menstrual cycle, it’s normal that you will be concerned something’s wrong.

Menstrual period in most girls will last for about five days, and then, your body starts preparing for ovulation.

Ovulation is the rupture of the most mature follicle, either on the right or left ovary, with the subsequent discharge of an egg into the fallopian tube.

Before ovulation occurs, there is a surge in hormones that control the development of about 20 follicles. The hormone, follicle stimulating hormone, causes your follicles to grow and mature till about a week or two after the end of your period when only one follicle (called the dominant follicle) ruptures and releases an egg.

Just before ovulation will take place, there is a rise in both estrogen and luteinizing hormones. It is believed hormone changes that occur around the time of ovulation cause spotting. Also, during ovulation, bleeding may result from rupture of an ovarian follicle.

Generally, bleeding from an ovarian follicle is normal, and it’s only a small amount of blood that mixes with your vaginal discharge and often goes unnoticed. However, if you have heavy bleeding, feel dizzy, or have severe pain, you should see your doctor or go to the emergency room.

Some women will notice their vaginal discharge now changes to a pink or brown color, and in some women, they may see a black discharge after ovulation.

These change to your discharge is because fresh red blood (at the time of ovulation) turns brownish or dark as it moves through your womb, cervix, and towards your vagina.

Here’s an email I received for Benny,

Hi Dunn

Thanks for the response to my previous email, but I still need help.

I noticed signs of ovulation three days ago and surprisingly, I am spotting 2 days after ovulation.

Is mild bleeding normal after ovulation, or is this a sign I am pregnant?

Just like Benny, spotting a day or two after ovulation can cause women to panic, but most of the time you shouldn’t.

Here are signs of ovulation that are common

Apart from vaginal bleeding, other signs can tell if you are ovulating. They are:

1. Watery cervical mucus

Your vaginal discharge can be watery, thick, creamy, jelly-like or sticky. It all depends on the effect of hormones.

After your period ends, and before ovulation begins, vaginal discharge is creamy and thick.

Around ovulation, there is a surge in estrogen hormone that increases your libido, and also, causes your vaginal discharge to be clear and watery.

If you notice spotting around this time, likely you’ve ovulated.

2. Pain in your lower abdomen

There are many reason women experience mid cycle pain; Ovulation is the commonest.

During ovulation stretching and rupture of the ovarian follicle causes pain in the left or right abdomen. Usually, this pain stops in few days.

Other signs of ovulation are feeling wet with more urge for sex, pain in both breasts, feeling bloated, and elevated basal body temperature.

Other causes of spotting after ovulation before period

While it’s likely spotting 3 days after ovulation is because of ovulation bleeding, if you are spotting 10 days after ovulation, or throughout your menstrual cycle, it could be due to pregnancy or a health problem.

Here are other reasons you are spotting after ovulation.

1. Pregnancy

While a majority of women that get pregnant will not experience spotting as a sign, studies suggest that roughly 1 in 4 to 1 in 3 pregnant women may notice some light implantation bleeding after ovulation has occurred. (See Cleveland Clinic – Implantation bleeding and Mayo Clinic – Implantation bleeding.)

After the release of an egg into the fallopian tube, the egg usually survives for about 12–24 hours before it dies. During this time (and in the few days before ovulation), if you have sexual intercourse, sperm moves quickly to your fallopian tube and fertilizes your egg. Sperm can live up to 5 days inside your reproductive tract.

After an egg is fertilized, it forms your baby (known medically as the embryo). The embryo starts to divide and finally moves into the uterus where it digs and burrows into the endometrial lining that coats the inner wall of the uterus.

As the embryo attaches itself, slight bleeding can happen, which may later be seen at your vagina as a pink, brown, or occasionally dark discharge. In some women, spotting will hardly be noticed. Heavy bleeding like a period is not typical for implantation bleeding and should be checked by a doctor.

The truth is, pregnancy spotting after ovulation usually occurs a few days before your next menstrual period, about 6–12 days after ovulation, and you may only see a light brown or pink discharge.

Other signs to show you are pregnant are

Implantation timing

It’s important you know when you are spotting after ovulation. If your light spotting is right after ovulation, it’s very unlikely to be implantation bleeding. Implantation bleeding usually occurs about 10–14 days after conception (around the time your period is due), is light, and not like your usual period bleeding.

Breast tenderness

Another easy sign of pregnancy is pain on the sides or center of your breast when touched. You will now be aware of you breast more often than normal because they are now heavier.

These breast changes occur because pregnancy hormones cause your ducts to increase and become more sensitive to pain.

Nausea and vomiting

It’s also common that you will feel like throwing up in early pregnancy. If you do, together with light vaginal bleeding around the time your period is due, it may be an early sign of pregnancy, but other illnesses can cause this too.

Missed period

A missed period can occur for many reasons, and if you are pregnant, your period will not come when due. This is because pregnancy hormones, estrogen, and progesterone, will cause your period to absent throughout pregnancy.

Can I take a pregnancy test?

Women that are expecting a baby need an early hint if they are pregnant. Apart from pregnancy symptoms (breast pain, missed period, vomiting, mood changes), a pregnancy test is crucial to identify if you are pregnant or not.

But you should also be aware of the setbacks associated with an early pregnancy test. If you get a negative pregnancy test right after implantation spotting, it still does not mean you may not be pregnant.

Most home urine pregnancy tests are most accurate from the day your period is due or about 14 days after ovulation. If you test too early, your hCG may still be low and give a false negative, so be patient and re-test again if your period does not come. (See Cleveland Clinic – Pregnancy test.)

It’s better to observe for pregnancy symptoms and watch if your period does not show up. If you’ve missed your period, take a pregnancy test.

2. Uterine fibroid

If you are spotting all the time, it could be due to a submucous uterine fibroid or fibroid polyp.

Fibroids are growth in the uterus that is common in young women, especially those more than 30 years. As you grow older and approach menopause, fibroids often shrink because estrogen levels fall, but this is not true for everyone.

The truth is, most women that have fibroid will not even know, and most often, will not have any symptoms. If you do, you will experience spotting from time to time, with a heavy or light vaginal bleeding.

Other symptoms of uterine fibroid are

  • Heavy menstrual bleeding

  • Pressure in your lower abdomen and pelvic areas

  • Lower abdominal pain

  • Pressure signs (constipation, frequent urination) are due to effect of a large uterine fibroid

  • Abdominal swelling

(For more, see Cleveland Clinic – Uterine fibroids.)

3. After taking emergency contraceptives

Occasionally, while you are trying to avoid pregnancy, you may have taken Postinor, Plan B, or early morning pills after an unprotected sexual activity.

These medications act mainly by delaying your ovulation and also make your vaginal discharge unfavorable for sperm transport and survival.

In some women, spotting can occur after taking medication. This is a common side effect and usually stops within days or by your next period, but if bleeding is very heavy, lasts more than a week, or you feel unwell, you should see your doctor. (See Cleveland Clinic – Morning After Pill.)

4. After taking birth control medications

If you already been on birth control pills for a months or weeks, spotting may occur if you changed to a new pill, suddenly stop taking medications, missed medication for days or if you are taking low dose estrogen pills.

Talk to your doctor if bleeding is heavy or continues for many weeks; otherwise, a light spotting after few months of starting birth control is not unusual.

5. Recent abortion

Bleeding after medical or surgical abortion is common. So, if you recently had your baby terminated through drugs or surgery (D & C), light vaginal bleeding is common and may last for days to a couple of weeks. If you soak two or more pads per hour, have fever, foul discharge, or severe pain, you must see a doctor urgently. (See WHO’s post-abortion advice summarised here.)

6. Vaginal infections

Pelvic and vaginal infections are common causes of vaginal spotting and cramps. Symptoms of infections are

You should see a doctor if you have these symptoms together with spotting.

What does spotting 4 days after ovulation mean?

If you’ve passed ovulation and experience light bleeding 4 days later, it may still be related to ovulation bleeding or normal hormonal changes.

Remember that pregnancy spotting (implantation bleeding) usually occurs later in your menstrual cycle and just before your menstrual period. So don’t panic its pregnancy.

What does spotting 5 days after ovulation mean?

If you have to bleed 5 days after ovulation, it can still be ovulation blood or old blood taking time to come out.

It takes some time for blood to move through your cervix to your vagina. This spotting is often dark or brown and usually nothing serious if it is light and stops quickly.

Spotting 6–7 days after ovulation, am I pregnant?

After ovulation, your fertilized ovum is moved slowly to your womb within about 6 to 12 days, and then implantation occurs.

Spotting around 7 days after ovulation could be an early pregnancy sign (implantation bleeding), but it can also be hormonal. Don’t take a test very quickly. Wait till you’ve missed your period and take a pregnancy test for a more reliable result.

Spotting 8 days after ovulation, can I take a pregnancy test?

Yes, you can. However, an 8-day post-ovulation test can still be negative even if you are pregnant. If it’s negative and you also feel exhausted, fatigued, breast pain, body weakness, it’s advisable to delay further test till after missing your period and then test again.
