What is Ovulation?

Ovulation is a monthly process, in which a woman’s ovaries produce an egg, which when fertilized, helps in the final goal of conception.

Importance of Ovulation

When you’re trying to get pregnant, ovulation is of utmost importance since that’s the time you’re most fertile. Having unprotected sex during this period of your menstrual cycle can increase the chances of getting pregnant. However, if you miss your fertile window, you'll have to wait until the next cycle to try again. Hence, you must keep track of your ovulation days in order to plan your family.

However, in case, you’re already a mother and wish to prevent an unwanted pregnancy, you must abstain from having sex during your fertile days. Many times, new mothers do not get their periods while they are breastfeeding & have this misconception that they are not ovulating. But this is not the case. Even if your body is not shedding the dirty blood each month, you still continue to ovulate & be fertile. The milk producing hormone prolactin is produced in an increased amount during breastfeeding & the levels of estrogen & progesterone are decreased due to this. Once your baby starts weaning, the levels of prolactin go down & your cycle returns back to normal.

How Long Does the Ovulation Period Last?

The ovulation period normally lasts between 12 and 48 hours. If you indulge in unprotected sex and as a result the egg & sperm are able to meet, then this egg can get fertilized, leading to conception. According to The American Pregnancy Association & various other research journals, the sperm can remain in a woman's reproductive system for up to 5 days. It also indicates that a woman is potentially fertile for up to 10 days after ovulation.

Late Ovulation: Causes, Symptoms & Effect

Causes

Ovulation can be late or absent due to an imbalance in your hormones but that doesn't mean that you're infertile. If you ovulate between days 21-35 of your cycle, then you might have no clue about your next menstrual cycle. If you're stressed and wondering if there are any chances of getting pregnant after a delayed or late ovulation, then you don't have to worry. Most of the time tracking your menstrual cycle and ovulation window can be a daunting task and for that, you can take help from a fertility expert.
Let's find out what causes late ovulation: 

  • Stress

    Stress of any kind be it physical, mental, or emotional, is bad for your health and fertility. It causes menstrual disorders in women because of poor hormonal health.

  • Thyroid Disorders

    A woman is said to be fertile when the pituitary gland is creating hormones. Even if the woman is ready to conceive, thyroid disorders like Hypothyroidism or Hyperthyroidism affect the natural process and creates a problem in the ovulation cycle. Irregular periods can happen due to Hyperprolactinemia (When hormone prolactin is secreted excessively).

  • Breasfeeding

    Prolactin is an essential hormone that produces breast milk and that also lowers fertility in a woman’s body during lactation. It's normal for nursing mothers to get an irregular menstrual cycle. 

  • PCOS (Polycystic Ovary Syndrome)

    PCOS affects the ovaries because testosterone is overproduced. It affects the functioning of ovaries by producing an excess of male hormones in a woman’s body, weight gain, irregular menstrual cycle, enlarged ovaries, and small cysts are built up in ovaries. Women with PCOS have to face many complications when trying to conceive.  

  • Medications

    Certain drugs and medications like steroids, marijuana, cocaine, some antipsychotic medication, and nonsteroidal anti-inflammatories can restrain your ovulation cycle.

Symptoms

Some of the common symptoms of delayed or late ovulation are:

  • Vaginal Discharge

    Changes in the vaginal discharge and increased cervical mucus, which resembles egg whites and appears to be stretchy and clear.  

  • Spotting

    When the ovulation is late, some women may experience spotting.

  • BBT

    Increase in basal body temperature.

  • Pain in the lower abdomen

    Pain at one side of your tummy or breakthrough bleeding. It is also called Mittelschmerz.  

Effects

After knowing about the causes and common symptoms of late ovulation, let's find out how does it affects conception and fertility: 

  • Difficulty in tracking your menstrual cycles  

  • Fluctuation in hormonal levels and late maturity of eggs

  • Increase in breast sensitivity

  • Heightened sex drive  

  • Longer wait time for sperms to get fertilized  

  • Release of immature eggs 

When should you see a doctor?

Many couples are hesitant to visit a gynecologist & obstetrician because they lack knowledge and don't know when they should consult one. You should consult a fertility expert if:

  • You’ve been trying to conceive for the last 1 year

  • You experience abnormal bleeding and excruciating pain during periods

  • You’ve not had a menstrual cycle for the last 90 days
