Cramping After Ovulation:Am I pregnant?

Two days ago, while in my weekly Obs/Gyn Clinic, I met a young lady that was concerned about her health. She is in her mid-20s, and she was worried about abdominal cramping after ovulation.

She has a boyfriend and was actively involved in sexual intercourse. Like every other lady, she was worried that abdominal cramps after her ovulation might mean something serious.

If you are experiencing mild cramps after ovulation, there is usually no reason to panic. However, very severe pain, pain that keeps getting worse, heavy bleeding or feeling very unwell should be checked by a doctor quickly. nhs.uk+1

Are you trying to conceive? If you are, cramping after ovulation can sometimes be an early sign of pregnancy, but most cramps in this period are not due to pregnancy.

However, it is crucial you perfectly understand the timing of ovulation. This is because there are other causes of abdominal cramps that are not due to ovulation.

This article explains how to identify ovulation, the reason why cramps after ovulation occur, and possibly other reasons why you have pain in your abdomen after ovulation.

What is ovulation?

Ovulation is the monthly discharge (release) of an egg from either the right or the left ovaries.

This means, at a specified time in your menstrual cycle, your body signals your ovaries to release an egg into the fallopian tubes that will eventually fuse with a sperm to form an embryo.

The process of ovulation is controlled by numerous hormones mainly follicle stimulating hormone (FSH), luteinizing hormone, estrogen, and progesterone.

The FSH works mainly by stimulating the growth of small follicles in the ovaries. These follicles, about twenty in number, continue to grow with the production of estrogen.

Towards the time of ovulation, just one follicle becomes dominant and mature. This follicle is called the Graafian follicle and is released at the time of ovulation.

After ovulation occurs, there is a corresponding change in the level of hormones in your body. The ruptured follicle forms what is called the corpus luteum, which mainly works to produces progesterone and small amounts of estrogen.

This means before ovulation occurs, estrogen is dominant, while after ovulation, there is a rise in the level of progesterone hormone.

How to correctly understand when ovulation occurs

The hormonal changes that happen before or after ovulation are the primary reasons you have abdominal cramps. But, as mentioned earlier on, it is important we identify when ovulation occurs to be sure abdominal pain is due to ovulation.

Here are symptoms you will experience just before ovulation happens:

Wet, watery, stretchy vaginal discharge

Now, this is one of the easiest ways to tell that you are about to ovulate. And, for a fact, it is as simple as dipping your fingers into your vaginal canal.

If your vagina discharge looks and feel watery, and you can actually stretch it between your fingers, that’s a sign that you are in your ovulation period. This type of mucus helps sperm move easily and is called “fertile cervical mucus.” Mayo Clinic+1

Light vaginal spotting

Another way to tell you are in your ovulation period is light vaginal spotting in the middle of your menstrual cycle.

The middle of your menstrual cycle is often about 2 weeks before your next period (for example, around day 14 in a classic 28-day cycle), but this can be earlier or later if your cycles are short or long. So, if around this time you notice mild vaginal bleeding, it may be due to ovulation spotting.

However, you need to be cautious still as there are other causes of vaginal spotting. Mid-cycle vaginal spotting due to ovulation is usually light and lasts for a few days at most. If spotting is heavy, lasts long, or keeps coming back, you should talk to your doctor. nhs.uk+1

Other signs of ovulation are an increased urge to have intercourse, bilateral breast pain, increased basal temperature, and a high and soft cervix.

What causes cramping after ovulation?

Now, since we’ve already identified when ovulation happens in the menstrual cycle, here are the most common reasons you will have cramps after your ovulation:

1. Ovulation cramps

One other symptom of ovulation is pain on the left or right side of the abdomen. This pain, also called mittelschmerz pain, may occur before, during, or shortly after ovulation has occurred. Mayo Clinic+1

Cramps before ovulation happen as the follicle stimulating hormone and estrogen cause growth of the follicles at the ovaries. At this time, it is possible that you may experience some form of pain in the left or right side of the abdomen depending on which ovary is releasing an egg.

Cramps during ovulation happen as the matured follicle ruptures and releases its content into the abdominal space. Within each follicle is the egg to be released, and also, clear fluid or blood.

During ovulation and rupture of the follicle, the content of the follicle is released into the abdominal cavity, causing irritation and pain.

Cramps after ovulation occur due to spasm and contractions of the fallopian tube as the “released egg” is slowly transported into the body of the uterus.

For most women, ovulation pain is mild, one-sided, and lasts from a few minutes to 1–2 days.

How to be sure it is ovulation pain (and not something else)

If you experience ovulation cramping and you are worried, here’s how to easily know if it is due to ovulation.

Ovulation timing

Ovulation pain occurs around your ovulation. This means it usually happens in the middle of your menstrual cycle, roughly 12–16 days before your next period. nhs.uk+1

For example, if you have a 28-day menstrual cycle, ovulation pain will likely happen around day-14 of your menstrual cycle.

If pain occurs just after you the end of your period or right before your next period, then it is less likely to be due to ovulation and may be caused by something else. This is especially true if your cycles are very irregular.

The severity and duration of pain

Another way to easily tell if it is ovulation pain is the duration of the pain. Yes, ovulation pain is short-lived. In fact, for most women, the pain subsides after 24 hours. At most, you may experience discomfort for about two days, which will subside on its own. Mayo Clinic+1

So, if you are experiencing pain for days and weeks after your ovulation, it is likely to be something else. You should see your doctor for help.

The location of the pain

Another easy way to tell if you are experiencing ovulation pain or not is the location of the pain. Ovulation pain is usually in your pelvic area or lower abdomen and can radiate to the back.

Pain is usually on one side of the abdomen. This means, if you have pain that spans through your whole lower abdomen, or comes with fever, vomiting, very painful sex, or heavy bleeding, it may not be as a result of ovulation and needs medical review.

2. Pregnancy

Is cramps after ovulation a sign of pregnancy? This is a common question I get from my patients trying to conceive. So, let me explain.

There are different signs of pregnancy. Cramps after ovulation can be one of them, but timing is crucial, and many women never notice implantation cramps at all. Medical News Today+1

Abdominal pain due to ovulation happens before, during, and around day 1 or day 2 after ovulation. At this time, as already mentioned, spasm at the fallopian tube causes mild abdominal pain.

During pregnancy, belly cramps that happen before your missed period are usually due to implantation. Implantation occurs when your fertilized egg digs into the thickened inner lining of the uterus called endometrium.

This can cause slight bleeding called implantation spotting, and also, mild cramps in the lower abdomen. Implantation most often happens about 6–10 days after ovulation, not the next day. Medical News Today+2PubMed+2

If you think you are pregnant, here’s a simple checklist to help you

1. You’ve had intercourse

To get pregnant, you must have had intercourse. And most importantly, you must have had unprotected intercourse during your ovulation period and fertile window (about 5 days before ovulation until 1 day after ovulation). ACOG+1

If you are sure when you last had unprotected intercourse, you can use a menstrual cycle calculator to check if it falls within your fertile period.

If you did have intercourse in your fertile period and now have cramps, it could be an early sign of pregnancy, but it could also be normal ovulation pain or something else.

2. Cramps occur just before the next period

The timing of pregnancy cramps is crucial. For ovulation cramps, it happens before, during, and just after ovulation. However, if pregnant, abdominal cramps related to implantation usually occur about 6 to 10 days after ovulation (and sometimes up to 12 days). Medical News Today+1

This is because it takes a while for the fertilized egg to be transported from the fallopian tube and implanted into the uterus. In some women, it may take around 6 days, while it may take up to 10–12 days for others.

In other words, if you have cramps a day or two after ovulation, pregnancy from implantation is very unlikely at that time. Cramps 1–4 days after ovulation are much more likely to be due to ovulation itself or another cause, even though you may already technically be pregnant from fertilization.

At the earliest, noticeable pregnancy-related (implantation) cramps usually occur around 6–10 days after ovulation, often close to the time your next period is expected.

3. You will experience other symptoms of pregnancy

Just like ovulation, if you are pregnant, you may experience other early signs of pregnancy. These include breast tenderness, fatigue, mild nausea, food aversions or cravings, increased urination, headache, mood swings, and sometimes light spotting from implantation. Cleveland Clinic+1

If you do, and you are yet to miss your period, you can take a pregnancy test — but remember that it may still be negative if carried out too early. For the most accurate result, most major health organizations advise taking a urine pregnancy test from the first day of a missed period or about two weeks after ovulation. Cleveland Clinic+1

So, it is important you take a test after you’ve missed your period, and repeat it later or see your doctor if you are unsure.
