Early Ovulation and Pregnancy: Causes, Symptoms and Treatments

What Is Considered EARLY ovulation?

Ovulating early is when a woman releases an egg from one of her ovaries well before the expected time. 

For some reasons women have been taught they ovulate right in the middle of their menstrual cycle on day 14, and if you have a 28 day cycle for instance you would think that is true.

This is not always true. Ovulation can occur early or even late. In general ovulation can occur between day 12-16 even for a woman with a 28th day menstrual cycle.​

Women who ovulate too early are known to have a short follicular phase.

Follicular phase is the first half of your menstrual cycle. It is the time from the first day of your period to the day you ovulate.

Normally the follicular phase should be 12-16 days long. It is during this phase that the egg grows and matures. 

Ovulation that is early means your follicular phase is less than 12 days which means you have a short follicular phase. And you could have issues getting pregnant.

short follicular phase

​The eggs released during an premature ovulation cycle may not be fully matured. This immature eggs  have low quality and will have problems getting fertilised.

Can You Ovulate Early in your cycle?

 Yes it is possible. 

​If you are trying to conceive, constantly ovulating too early can lead to fertility issues.

By Ovulating too early I mean ovulating less than Day 12 in your monthly cycle.

Ovulating within the range of Day 12-16  is normal.​ And fertilisation is possible because the eggs produced during this normal ovulation are matured.

Causes Of PreMature Ovulation

So let's find out what causes  Ovulation before the appropriate time?

Hormonal Imbalance: 

Having an hormonal imbalance can disrupt the length of woman's menstrual cycle.   

The Follicle Stimulating Hormone (FSH)  causes the egg to be matured in the ovary and the Luteinizing Hormone(LH) causes the matured egg to be released from the ovary.

The hypothalamus and the pituitary gland are both responsible for regulating the levels of FSH and the LH produced at the beginning of your menstrual cycle. 

Any deficiencies or excess in the FSH and LH can lead to ovulatory Dysfunction.

High FSH has been linked to ovulation too early and a short luteal phase.​

Ovarian Decline:

Usually women are born with all the eggs they would ever release. Right from birth women are born with approximately 2 million eggs. 

During each menstrual ​cycle, hundreds of these eggs die because only one matures except if the woman hyper-ovulates i.e releases more than one egg during ovulation.

According to a study, scientist have found that women lose more than 90% of their eggs by age 30.

As a woman approaches menopause, the body produces more Follicle stimulating hormone to compensate for the decline in egg. These excess FSH leads to ovulating earlier than usual and a short follicular phase.

Short Follicular Phase:

A constantly short follicular phase each month causes infertility in the long term.

As earlier discussed egg produced in a short follicular phase are usually immature and have difficulty getting fertilised or implanting to the uterus.

A shorten 1st part of the menstrual cycle is a leading cause of ovulating too early and infertility.​


According to research, smoking causes ovulation problems and thus affects female fertility.

The study shows that women who smoke heavily at least 20 cigarettes per day have a short menstrual cycles.​

A woman's reproductive health can be affected by the toxins in cigarette smoke.

Constantly exposing yourself to cigarette smoke may affect your hormones functionalities.

Heavy Alcohol Consumption

Heavy alcohol consumption has been linked to both early arrival of ovulation and short follicular phase.


Caffeine consumption also has an effect on a woman's reproductive health and hormones.

According to the published research an excessive consumption of caffine can lead to a short follicular phase thus an early than normal ovulation.

SIGNS AND SYMPTOMS OF ovulating earlier than normal/usual


To find out if you have a short follicular phase it is advised you monitor your cycle for 3 months.

If you have a 28 day cycle you should expect ovulation to be between Day 12 -16. If you have a 30 day cycle you should expect ovulation to be between Day 13-17.

 If your start experiencing  any one of these ovulation signs just a few days after your period has ended then you most likely have an earlier than normal ovulation:

  1. Cervical Mucus Changes
  2. LH Levels in urine
  3. Breast Tenderness
  4. Rise in Basal Body Temperature
  5. Positive Sign from Ovulation Predictor Kits
  6. Breast Tenderness
  7. Rise in Basal Body Temperature
  8. Increased sexual Libido
  9. Ovulation Cramps

Remember having just once in a while earlier than usual ovulation is ok. Ovulating too early constantly for 3 months in a row could lead to fertility issues.

Why is My Period Early?

Periods usually come around 2 weeks after ovulation. But if your period comes earlier than expected it could be caused by one of the followings:

  1. Stress
  2. Ovulating before a fully matured egg is ready and short Luteal Phase
  3. Sudden weight loss or Sudden weight gain​
  4. Morning after Pill
  5. Birth Control
  6. Sexually Transmitted diseases
  7. Change in normal daily activities

ovulation early and Getting Pregnant

What are the Chances of pregnancy if you ovulate early?

If you ovulate early in your menstrual cycle, ​your chances of getting pregnant or getting a BFP (Big Fat Positive) is reduced because the eggs produced when your   ovulation comes too early are immature.

Immature eggs have difficulty with fertilisation and implantation when compared to eggs that are released when they are fully matured.

what is my Egg Quality if I ovulated early?

Eggs produced in a cycle where you ovulated early, for instance let's say you ovulated on Day 8, Day 9 or Day 10 of your menstrual cycle.

These eggs are of lower egg quality because they have not matured properly.

If the egg doesn't get adequate time to grow and develop it won't be fully matured at the time it is been released.

Ovulating early  in cycle usually results in poor conception due to the lower quality of egg produced.​

Your chances of getting pregnant are reduced but not impossible.

Ovulating early is a sign of decreased ovarian reserve. The less eggs you have, the earlier you ovulate.

Ovulating too early After Miscarriage

It is possible for women to ovulate early from time to time over their menstrual life-cycle.

If you just had a miscarriage and you are trying to conceive it is advisable you wait for one full cycle to complete before you try.

If you previously had a normal ovulation but after miscarriage you are constantly ovulating earlier than normal. It could be caused stress, environmental factors or even hormonal imbalance.
