It’s possible to be anxious if you don’t menstruate on schedule every month. You may begin to question your health. However, did you realize that you can still ovulate late? We’ll talk about what causes delayed ovulation and offer some suggestions for correcting the problem in this blog article. We’ll also give you some ideas on how to improve your chances of getting pregnant if you’re having trouble conceiving.

What is late ovulation?

Delayed or late ovulation occurs when ovulation takes place after day 21 of your menstrual cycle. Ovulation is the release of a mature egg from an ovary. The monthly increase and decrease in hormones such as progesterone and estrogen triggers it.

  • estrogen
  • progesterone
  • luteinizing hormone
  • follicle-stimulating hormone

Ovulation generally occurs halfway through your menstrual cycle. The usual cycle lasts 28 days, so ovulation most often happens on day 14 of the cycle. However, there is a lot of variabilities.

What causes late ovulation?

The menstrual cycle is divided into three phases:

  • the follicular phase, in which the ovarian follicles develop and an egg matures in anticipation of its release
  • ovulation
  • the luteal phase, in which the follicle closes and hormones are released to trigger the shedding of the uterine lining unless pregnancy has occurred

The luteal phase, which lasts around 14 days after ovulation and is characterized by the discharge of an egg (which is only a few hours long), maybe anywhere from 10 to 16 days long. If the follicular phase takes longer, ovulation will be delayed or even absent.

Ovulation occurs near the end of a female’s cycle. Ovulation is induced by both temporary and long-term hormone imbalances, depending on the cause. The following are some examples of factors that might induce a hormonal imbalance:


irregular ovulation

Certain medications and drugs can inhibit ovulation, including:

  • long-term use of nonsteroidal anti-inflammatories (such as Advil or Motrin)
  • some antipsychotic medications
  • marijuana
  • cocaine

In a study, scientists investigated the impact of meloxicam, which is used to treat arthritis and can lead to infertility. Participants who took meloxicam had a five-day delay in follicular rupture and egg release when compared to those who received a placebo.

Extreme stress, whether physical or psychological, has the capacity to have a negative influence in a variety of ways. Following an 8.0 earthquake in China, researchers found that menstrual issues among Chinese ladies increased by more than 200 percent.

Prolactin inhibits ovulation and menstruation, two functions of the female reproductive system. If you solely breastfeed, your menstrual cycle may be disrupted.

However, breastfeeding should not be used as a contraceptive. Ovulation can happen up to two weeks before the start of menses.

Thyroid disease

The thyroid gland has a significant influence on the pituitary gland. The pituitary is a brain component that produces some of the hormones necessary for ovulation. An underactive or overactive thyroid might prevent or delay ovulation, respectively.

Polycystic ovary syndrome (PCOS)

PCOS is a disease in which too much testosterone is formed. Because of an overabundance of testosterone, the ovaries are unable to release an egg. One of the most typical PCOS symptoms is an irregularity with your menstrual cycle.

Although polycystic ovary syndrome (PCOS) is a rare condition affecting 1 in 10 women, it is extremely common among certain racial and ethnic groups.

How does it affect menstruation?

Delayed ovulation can cause menstrual irregularity.

Many women who have late ovulation experience a lot of bleeding during their period. The National Health Service (NHS) in the United Kingdom explains that hormone levels rise during the first part of the menstrual cycle, causing the uterine lining to thicken.

Ovulation is the process by which an ovum is released from an ovarian follicle and enters the fallopian tube. The release of this egg into the fallopian tube also causes a surge in progesterone, as well as LH (luteinizing hormone). If fertilization does not occur, however, there is no egg to be fertilized. So estrogen continues to emerge and blood flows into the uterine lining instead.

The lining becomes liquefied and exits the body as a heavier-than-normal menstrual flow at some time.

Fertility and chances of conceiving

Ovulation does not occur if fertilization has not occurred. Late ovulation might have an impact on a woman’s fertility and ability to conceive.

Ovulation difficulties, according to the American College of Obstetricians and Gynecologists (ACOG), are the most common reasons for infertility in women.

Women who have long or irregular cycles have a harder time determining ovulation. As a result, they find it difficult to conceive because they have no means of knowing when sex is appropriate.

However, ovulation does not indicate that you are pregnant. Many women who have irregular ovulation give birth to healthy babies.

Many women have difficulty conceiving due to a medical problem that inhibits ovulation, such as polycystic ovarian syndrome (PCOS), hyperprolactinemia, or hypothyroidism.

When to see a doctor

See your doctor if you have any questions about your menstrual cycle, ovulation, or fertility.

The majority of people who suffer a stroke could recover fully. The sooner a person receives treatment, the more likely it is that he or she will improve. This is particularly true of fertility, which deteriorates with age, according to ACOG.

It is also important to see a doctor if any of the following apply:

  • menstrual cycles are less than 21 days or longer than 40 days
  • sudden changes occur to the menstrual cycle
  • periods suddenly stop without any apparent reason
  • heavy menstrual bleeding occurs
  • severe period pains occur
  • symptoms of PCOS, hypothyroidism, or hyperprolactinemia develop

Only persons under the age of 35 who haven’t conceived after 12 months of trying or those over the age of 35 who haven’t conceived after 6 months can attempt to conceive without using Clomid or other assisted reproductive technologies (ART).

What can you do if you ovulate late in your cycle?

If you have PCOS, metformin may be used to assist you in getting pregnant. Insulin resistance is common in women with PCOS, and metformin helps to boost the cells’ response to insulin. It also corrects hormonal imbalances. Your doctor might prescribe clomiphene citrate or letrozole, which can aid in ovulation by promoting egg development.

Many women with PCOS are overweight. If you’re obese, your doctor will almost certainly work with you to develop a weight-loss strategy. Losing just five pounds might improve your chances of ovulation and pregnancy by balancing out your hormone levels and increasing the odds of conception.

If your doctor suspects you have hyperprolactinemia, he or she will prescribe medicines to reduce prolactin production and shrink the tumor in your brain. If you have hypothyroidism, a pill can help regulate thyroid hormone levels. Both diseases allow the medication to control your cycles, allowing you to ovulate on a regular basis — which makes timing sex and getting pregnant much easier.

If your doctor thinks you have regular menstrual cycles with a short luteal phase, she could prescribe progesterone to extend the length of time your uterine lining is present each cycle, increasing the likelihood of your eggs attaching to the uterine wall. Clomiphene citrate may also be prescribed by your physician to induce ovulation.

Conclusion thoughts

It is possible to get pregnant without the aid of Clomid or other assisted reproductive technologies (ART) if you are under the age of 35 and have been trying to conceive for 12 months, or over the age of 35 and have been attempting to conceive for 6 months. If you don’t ovulate until late in your cycle, your doctor may give you drugs like Metformin, Clomiphene citrate, or letrozole to help you get pregnant.

If you have PCOS, many women are overweight, so your doctor will most likely collaborate with you on a weight-loss program if this is the case for you. Losing as little as five pounds might significantly improve your chances of ovulating and having a successful pregnancy.
