Ever wondered, “Can ovulation occur during pregnancy?” If you have, then you are among the millions of women who have had this thought at least once. When keeping yourself up to date with various aspects of pregnancy, you may come across scenarios or articles in various magazines or on the internet which talk about a woman getting pregnant with another child when she was already pregnant with one. Rarely does anyone take this seriously, but it might make you wonder if ovulation occurs during pregnancy in real life. So, is ovulation in pregnancy possible? Does that mean you will have more than one baby? If the question has piqued your interest, this article on pregnancy and ovulation will be eye-opening for you. Here, we will look at the answer to the question “Can you ovulate while pregnant?” and some more factors associated with it.

Can a Woman Ovulate During Pregnancy?

If you are wondering, “Do you ovulate when pregnant?”, here is the answer for you.

A straightforward answer to the possibility of ovulation while being pregnant is a simple NO. In scientific terms, ovulation is the process by which the ovaries release an egg during a menstrual cycle. This egg then travels through the fallopian tube and, if sperm is present, it will be fertilised. A fertilised egg then finds its way to the uterus, where it awaits implantation. If the egg doesn’t get fertilised, the uterine lining is shed. This shedding of the lining is what constitutes your period (1). Simple.

Now, when you are already pregnant, the body is aware of this and does not undertake any processes to release the egg or proceed with ovulation. The uterus, tubes and ovaries all form part of the same system, so the presence of an embryo automatically triggers these processes to shut down. The uterine lining is held in its place to support the growing baby, and you won’t have any more periods during your pregnancy.

Signs of Ovulation While Pregnant (Misconceptions Explained)

Many people believe they can ovulate while pregnant, but this is largely a misconception.

During pregnancy, hormones like progesterone and hCG suppress ovulation. The body prevents the release of new eggs. Symptoms like discharge or mild cramps may mimic ovulation, but they are simply pregnancy-related.

So, basically, ovulation typically does not occur during pregnancy.

What If the Ovulation Test Shows a Positive Result?

Despite this science, you might come across various sources that claim ovulation does occur during pregnancy. Or, you might take an ovulation test and get a positive result, post which your pregnancy could be confirmed. Both the positive test results may leave you confused. However, there’s one thing you ought to remember is that, just like pregnancy tests, the ovulation tests, too, work on the presence of a hormone. These tests do not actually check whether the ovaries are releasing an egg or not. And, since the hormones undergo a substantial change when pregnancy sets in, those levels might be a little too high, triggering the test to reveal a positive result for ovulation.

Therefore, a positive result for an ovulation test might purely be a result of hormonal fluctuations or even a faulty test, for that matter. In certain cases, your body might just be on the verge of getting pregnant or, unfortunately, on the verge of a miscarriage.

What If You Had a Period While Being Pregnant?

Along with ovulation, another worry that might plague pregnant mothers is whether a period can occur while they are pregnant. This, too, has no scientific basis. Periods, as mentioned earlier, are a result of shedding the lining of the uterus since there is no fertilised egg to house it in. Once you are pregnant, the uterus lining needs to stay put so that the embryo has the support to grow safely and develop into a proper fetus. So, no, you won’t get your period once you are pregnant (2).

That being said, there are chances you might spot a few drops of blood or light bleeding while you are pregnant, which is implantation bleeding (3). But this is quite different from the blood you usually see in your menstrual cycles, and this bleeding is a result of many other factors, such as ectopic pregnancy or miscarriage. If the bleeding feels thick and unusual, it may indicate a problem, and you should let your doctor know immediately.

What Is Superfetation and How Did it Occur?

Superfetation is an extremely rare condition in which a second pregnancy occurs while a woman is already pregnant. That means the female releases another egg and gets fertilised while the previously fertilised fetus is still developing in the uterus (4). It is extremely rare in humans and has been documented only a very few times. But it is common in animals like rodents and rabbits, and some primate species.

This means that in case of superfetation in human pregnancy, the uterus of a woman will contain two different fetuses at two different growth stages, each with its own placenta. In a rare extreme situation, the placentas may also merge, but their development is dependent on when implantation happens.

The time of delivery in such cases is very challenging as both fetuses need to be delivered. With a planned cesarean section, one baby is devlivered developed, and the other one is premature.

While the phenomenon of superfetation is likely rare, the literature has recorded certain cases (5). In a 2013 study, it is suggested that superfetation fetuses are usually conceived 2 to 4 weeks apart, so it is considered that this phenomenon likely happens within a short window of the first conception (6).

Risks of Superfetation

Here are the known risks of superfetation

1. Preterm Labour

One of the biggest concerns with this type of pregnancy is the risk of preterm labour. When the older baby reaches full term, and the uterus begins contracting, those same contractions can trigger the early delivery of the younger baby as well because they share the same womb, even if they have separate placentas.

2. Preterm Birth

The younger fetus may not be fully developed when the older one is ready for delivery.

3. C-section Delivery

Doctors usually plan ahead and schedule a caesarean section at a carefully chosen date. The goal is to time it so the younger baby has had enough time to develop and is strong enough to survive outside the womb safely.

4. Nutritional Deficiency

Another challenge is nutrition. Two babies at completely different stages of growth are essentially drawing from the same source of nourishment. This competition can lead to deficiencies and may result in one or both babies being born with a lower-than-normal birth weight.

5. Monitoring of Babies

Finally, keeping a close eye on both babies throughout the pregnancy is absolutely essential, but it’s easier said than done. Monitoring can get quite tricky, as getting a clear ultrasound image of both babies at once isn’t always straightforward. How well each baby shows up on a scan often depends on where the placentas are located and how the babies are positioned in the womb at any given time.

FAQs

1. What happens to sperm when you are already pregnant?

Sperm deposited in the vagina during penetrative vaginal sex get discharged from the body through the vaginal opening. Also, it does not harm the baby as the amniotic sac, placenta, and mucus plug covering the cervix have a protection system that’s specific about what goes in and stays out.

2. Do women lose eggs during pregnancy?

Women are born with approx. one to two million eggs. But the number gradually decreases with age. Once a woman starts her menstrual cycle, one egg is ovulated, and about 1,000 eggs are lost monthly. These numbers are not influenced by anything like pregnancy, being on birth control, or otherwise not ovulating.

Ovulation while pregnant is not a possibility since our biological processes are oriented in a way to shut off the ovulation cycle once the uterus has a fertilised egg to take care of. The only way to be absolutely sure of ovulation is to undergo intensive tests that check for multiple follicles or ultrasounds that determine if an egg has been released. The usual ovulation tests measure hormonal levels, which can very easily fluctuate during pregnancy. Therefore, it is best to put this question to rest and enjoy your newfound pregnancy with zest.
