What to Do if You Have Diarrhoea During Ovulation

Tracking your ovulation may be an effective method for achieving pregnancy. Considering that you may be suffering diarrhoea during ovulation, you may be asking whether there is a connection between ovulation and bowel movements. Can ovulation induce diarrhoea?

What Exactly Is Ovulation?

To comprehend why you may have diarrhoea or an upset stomach during ovulation, you must first grasp what ovulation is. The discharge of a mature egg from the ovaries into the fallopian tubes constitutes ovulation.

Diarrhoea and Ovulation

What Causes Diarrhoea During Ovulation?

Diarrhoea is considered one of the most unpleasant ovulation symptoms. To comprehend what causes ovulation diarrhoea, it is necessary to comprehend what prostaglandins are.

What Is a Prostaglandin?

Prostaglandins are a class of lipids synthesised at the location where they are required. The majority of cells in your body create prostaglandins, which are utilised to treat diseases and injuries.

Depending on the region of the body where they are generated, they also serve as signals that regulate other activities.

Prostaglandins contribute to the regulation of the female reproductive system and are involved in the regulation of the menstrual cycle, labour induction, and ovulation.

How Do Prostaglandins Cause Diarrhoea During Ovulation?

During ovulation, prostaglandins are secreted and have a role in the induction of the inflammatory response necessary for egg release from the follicle.

These prostaglandins begin to relax the smooth muscle tissue inside the uterus in order to facilitate the shedding of the uterine lining.

During ovulation, these very same prostaglandins may also cause the intestinal muscles to relax, which can result in loose stools.

Due to the drop in oestrogen and progesterone during this phase of your menstrual cycle, you may also get diarrhoea during your period. These loose bowel movements during menstruation are sometimes referred to as “period poops.”

Are There Other Causes of Diarrhoea During Ovulation?

Although hormonal changes and the production of prostaglandins during ovulation might induce diarrhoea, there are other causes as well.

Ectopic Pregnancy

Ectopic pregnancy might be a cause of diarrhoea during your ovulation window. An ectopic pregnancy is the implantation of a fertilised egg outside of the uterus, often inside one of the fallopian tubes.

Other ectopic pregnancy symptoms include:

  • Abdominal pain on one side
  • Pain during urination or bowel movements
  • Vomiting
  • Ache in the shoulder
  • Vaginal bleeding

An ectopic pregnancy is termed a medical emergency. If you believe that you are having an ectopic pregnancy, you should seek medical attention immediately.


Endometriosis– a disorder where the uterine lining develops in locations outside of the uterus (including the ovaries, vagina, fallopian tubes, intestine, rectum, cervix and area and the uterus)- may cause diarrhoea.

Irritable Bowel Syndrome

During ovulation, Irritable Bowel Syndrome, or IBS, may cause diarrhoea.

Symptoms of IBS include changes in bowel habits, bloated belly, the passage of excess gas, stomach discomfort or cramping, passing mucus from the rectum and feeling as if intestines are not empty after passing stools.


Progesterone, a hormone secreted by the ovaries, may produce constipation or diarrhoea in certain persons.

Your progesterone levels peak immediately before ovulation, and a high surge in progesterone might induce constipation. This suggests that constipation may occur during ovulation.


During ovulation and the period phase of your menstrual cycle, you may encounter digestive disorders such as constipation or diarrhoea. Listed below are some methods for alleviating stomach symptoms: 


Probiotics can treat digestive tract difficulties during ovulation

Probiotics are “good” living bacteria and yeasts. They may be used to aid with stomach disorders.

There are many different types of probiotic microorganisms. These include:

Bifidobacterium – This “good” bacteria may be found in various dairy products, and can assist to improve digestive difficulties.

Lactobacillus – Lactobacillus is one of the most prevalent probiotics, if not the most frequent. This probiotic is typically found in yoghurts. This sort of probiotic may be used to treat diarrhoea, and specific strains of the bacteria can benefit lactose-intolerant individuals.

Saccharomyces boulardii – This is a yeast included in probiotics that helps prevent or alleviate diarrhoea and other digestive issues.


Calcium can aid with intestinal health

Calcium may help to alleviate diarrhoea and other digestive troubles associated with PMS. Calcium may be obtained over the counter, or contained in a range of foods, such as eggs or milk.

Fibre for Digestive Tract Disorders

As fibre is not digested, it adds weight to faeces, therefore alleviating constipation. Spinach, barley, apples, bananas, beans, oats, grapes, oranges, and many more foods contain fibre. Different pharmaceutical supplements are also available, so speak to your doctor today to find out what’s best for you.
