Can Late Ovulation Affect Your Chances of Pregnancy?

Can Late Ovulation Affect Your Chances of Getting Pregnant?

Ovulation is the 21-day period when the egg gets released from the ovaries and travels down the fallopian tubes. When the sperm meets the egg, the zygote gets implanted into the uterus. The endometrial wall thickens as a result, and the pregnancy term begins. However, in many cases, fertilisation doesn’t happen, and the egg gets released from the uterus lining, leading to periods in women.

Usually, ovulation starts on Day 14 during the 28-day menstrual cycle, but sometimes due to a number of reasons, it may be delayed (late ovulation). In this article, we shall discuss this condition in a little more detail and how it might affect your chances of getting pregnant.

What Is Late Ovulation?

Late ovulation happens if you ovulate anywhere between the Day 21 and Day 35 mark. Ovulating late in the cycle doesn’t mean you’re infertile, but it does say that you don’t know when your next menstrual cycle will happen.

When the estrogen and progesterone hormones release along with the luteinizing hormone, and follicle-stimulating hormone, mature eggs get released from the ovaries. Menstrual cycles are typically 28 days long, but ovulation happens on day 14. However, sometimes this may take longer, sometimes more than a month, which is when it’s a good idea to look into your conception options and treatment.

If you’re stressing yourself wondering if there are chances of getting pregnant after delayed ovulation, worry no more. There are chances of conceiving even when a woman experiences delayed/ late ovulation. Most of the time, tracking the menstrual and ovulation cycle can help you figure out the days you’d ovulate. In some instances, a fertility expert can help diagnose the underlying cause of late ovulation and address the issue. Let’s take a look at what these causes could be.

What Are the Causes of Late Ovulation?

There are several causes linking late ovulation in women. Here we talk about some of the most common reasons for late ovulation:

1. Stress

Stress is one of the leading causes of menstrual disorders in women. Be it physical, emotional, or mental, stress is bad for you, and it’s not just with regards to fertility or hormonal health.

2. Thyroid Disorders

The pituitary gland is responsible for creating hormones that make a woman fertile and ready for conception. Thyroid disorders like hyperthyroidism or hypothyroidism affect this natural process, thus causing problems with ovulation. Hyperprolactinemia (excessive secretion of hormone prolactin) can also result in irregular periods which may affect your ovulation cycle.

3. Breastfeeding

Breastfeeding lowers fertility in women since the body is busy producing prolactin for more breast milk. It’s normal for nursing moms not to have any periods or undergo menstrual cycles when they breastfeed.


4. Polycystic Ovary Syndrome (PCOS)

Polycystic Ovary Syndrome affects the ovaries and alters its functioning. It is characterized by high levels of male hormones in women, enlargement of the ovaries, insulin resistance, weight gain, and irregular menstrual cycles. Women with PCOS do not experience periodic ovulation and face problems getting pregnant. 1 in 10 women is prone to PCOS. In short, PCOS is characterized by an imbalance in hormonal levels in women, sometimes even leading to the buildup of small cysts in the ovaries.

5. Medication and Substance Abuse

Medications like non-steroidal anti-inflammatory drugs, steroids, anti-psychotic substances, and drugs like marijuana and cocaine influence the menstrual cycle in women, thus tampering with the ovulation phase and halting it.

6. Excessive Physical Activity

Excessive physical activity, particularly running, can disrupt hormonal equilibrium. This is not solely attributed to weight loss but emphasises the importance of maintaining a harmonious balance in all aspects of life.

Each of these causes will show different signs. Read on to learn about the common symptoms of late ovulation.

What Are the Symptoms of Late Ovulation?

Some of the late ovulation and pregnancy symptoms in women include:

1. Vaginal Discharge

Change in vaginal discharge is a common occurrence in the case of late ovulation. The cervical mucus would appear to be clear and stretchy, like an egg white.

2. Spotting

Other than a change in the vaginal discharge, some women may also experience light spotting when the ovulation is late ovulation.

2. Heightened Basal Body Temperature

Basal body temperature is your default body temperature when you’re at rest or asleep. This will increase when you’re close to the ovulation phase or already underway. Monitor your temperature before you get out of bed and track it to identify if you’re ovulating.

3. Pain in the Lower Abdomen

Pain on the sides of the abdomen or the pelvic region could indicate that you will ovulate soon. Sometimes, the pain feels one-sided and sharp, and in other cases, breakthrough bleeding follows.

4. Hypogonadotropic Hypogonadism

This is a lesser-known cause of delayed ovulation, which can be a condition known as hypogonadotropic hypogonadism, which is a hormonal disorder that affects the pituitary gland’s ability to produce the necessary hormones for ovulation. This condition can result from various factors, including certain medications, tumours or genetic abnormalities. However, it’s important to emphasise that this is an uncommon cause. If you suspect you have delayed ovulation, it’s best to consult a healthcare professional for a thorough evaluation and diagnosis of reasons for late ovulation.

So you know what late ovulation is and what its causes and symptoms are. But does it affect fertility? Let’s find out more about late ovulation on pregnancy success.

How Late Ovulation Affects Fertility and Conception?

Late ovulation affects fertility and conception in the following ways:

  • One of the known effects of late ovulation on pregnancy is that you have a difficult time anticipating your menstrual cycles. This creates a challenge when you want to know the days you’d ovulate.
  • You’ll also have a harder time getting pregnant, and it may require multiple attempts by your partner to conceive successfully.

What Are the Possible Consequences of Delayed Ovulation?

Some of the possible consequences of delayed ovulation include:

  • A heightened sex drive and increase in breast sensitivity.
  • Difficulty in tracking your menstrual cycles.
  • Immature eggs may get released, which may not get implanted into the uterus.
  • Late maturity of eggs can cause the hormonal levels to go out of balance.
  • You may have to wait longer for the sperm to fertilize the egg since ovulation could happen around day 20 or beyond.

Many times, in spite of late ovulation, it is possible for a couple could get pregnant. Other times, women may have to track their ovulation, predict a window and try to get pregnant. You may consider using ovulation predictor kits to track your ovulation cycle. Follow the instructions provided along with the kit and do the tests early in the morning since that’s when the concentration of luteinizing hormone (LH) is most likely to be highest in the urine.

If you are still not able to conceive, there could be other factors affecting conception. Several couples delay consulting an expert because they don’t know when they should consult one. The next section should help you figure that out.

When to Consult a Fertility Expert for Medical Treatment?

You should consult a fertility expert for one of the following reasons if you are not able to conceive even after somehow tracking your ovulation cycle and trying to conceive several times –

  • You’ve been trying to conceive for a whole year without using any birth control pills.
  • You suspect your partner to be infertile.
  • You have been taking certain drugs, supplements, or medications.
  • You have any existing medical condition that is related to delayed ovulation.
  • You notice abnormal bleeding every few hours.
  • You experience excruciating pain in the abdomen during periods.
  • You haven’t had a period since the last 90 days.
  • Your menstrual cycles are shorter than 21 days or longer than 35 days.
  • You suspect you’re infertile or cannot conceive.
  • Your ultrasound scans turn out abnormal.
  • You have a history of tuberculosis endometriosis or any medical comorbidity.

All the information may seem daunting, but there are ways the condition can be managed to help you conceive. There are also treatments available to treat infertility due to late ovulation. Read on to know more.

Treatment for Late Ovulation

Treatment for delayed ovulation involves treating the medical issue that leads to late ovulation and also boosting reproductive health. Here are some ways late ovulation can be managed or treated.

1. Medication

If you have existing medical conditions like thyroid disorders or PCOS, your medical expert will likely create a treatment plan to treat them first. The medical expert may prescribe medication like Clomiphene (Clomid), letrozole, and human chorionic gonadotropins.

2. Beat Stress

Stress is one of the topmost causes of late ovulation. To tackle stress, you can take up some yoga, join a hobby class, and get those creative juices flowing. You can also practise relaxation or therapeutic routines like Tai Chi and Qi Gong if you feel stressed out a lot.

2. Get Enough Sleep

Too little sleep, insomnia, and sleep deprivation are known to mess with your hormonal levels, thus impacting your quality of life and ovulation cycle. Make sure to get enough sleep and take power naps throughout the day.

3. Avoid Pushing Yourself Too Hard

This means no vigorous exercise. Moderate exercise is fine if you’re overweight or obese but don’t be sedentary either. Strike for a good balance and stay active.


4. Healthy Diet

This means meeting your nutritional RDA and consuming plenty of fruits and vegetables. Add nuts and seeds, legumes and lentils and grass-fed meat to your diet. When eating healthy, be sure to take your supplements like folic acid and your prenatal vitamins. And lastly, don’t forget to stay hydrated.

5. Say “No” to Alcohol and Cigarettes

Excessive alcohol consumption and smoking may lead to late ovulation. They could thus impact your fertility and delay your chances of getting pregnant.


1. Can Late Ovulation Lead to Miscarriage?

Late ovulation can be associated with a slightly higher risk of miscarriage, particularly if the fertilised egg has less time to implant correctly in the uterus before a woman’s menstrual cycle begins. However, it’s essential to remember that many factors can contribute to miscarriage, and late ovulation is just one potential factor among many.

2. Can I Ovulate Late and Still Get Pregnant?

Yes, it is possible for a delayed ovulation and successful pregnancy. Many women ovulated late and got pregnant. However, delayed ovulation and pregnancy success are not common. Sperm can survive in the female reproductive tract for several days, so if you have unprotected intercourse before or shortly after ovulation, there is still a chance of fertilisation. It’s essential to be aware of your menstrual cycle and fertile days if you’re trying to conceive, as late ovulation can make your fertile window occur later in your cycle.

Not ovulating or being unable to get pregnant is a disheartening experience for many women, but don’t lose hope. Wait patiently and follow your medical expert’s treatment plan, things may work out in the end. Every woman is different, which means sometimes, you just have to be patient before you see good results. There are cases where women start ovulating after a whole month, so remember that delayed ovulation doesn’t necessarily mean a woman is infertile. It may take some time, but if you follow what your doctor says, you will be fine.
