According to scientific research women have their monthly period 11 to 13 times in a year. Some women have more or some have fewer. It is totally normal to have irregular periods since it can take up to years for the menstrual cycle to find a balance.

We give you 7 common reasons that might be the cause of your missed period.
1. Excessive Weight Loss Or Gain

A study of University of Michigan explains women are likely to miss their period when they’re losing weight due to external factors. But, it is also proven that obesity can disturb your cycle and hormones too which can inhibit your periods.
2. Chronic And Emotional Stress

Stress does not only mentally bring emotional baggage with itself, but also physically. It can literally make your system weak. Excessive stress is a reason why you could be missing your period. Your brain receives anxiety triggers and starts obstructing the functional system in the body.
3. Illness
Your periods can decide to take a break when you have an upset stomach or you’re ill. Missing periods does not only have disadvantages but also advantages! Imagine experiencing extra cramps whilst feeling ill or vomiting.
4. Hormone Problems
When your hormones are disrupted, the chances of missing your period is higher than normal. Hormonal imbalance with thyroid or prolactin can cause missed periods too. This can easily be detected by consulting a doctor and taking blood tests.

5. Breastfeeding
Women who have just given birth and are in the process of breastfeeding are likely to miss their period until the completion of breastfeeding.

6. Polycystic Ovary Syndrome
You might miss your period if you have a condition called PCOs (Polycystic Ovary Syndrome) that causes your body to produce more of the male hormone androgen. Cysts might form on the ovaries due to the hormonal imbalance. This can cause your period to stop or become irregular.
7. Birth Control
Birth control pills contain hormones that prevent ovaries from releasing eggs. The menstrual cycle might take about 6 months to become consistent once you go on or off birth control pills. Other types of contraceptives (other than the pill) can also cause missed periods.
Long story short: Missing your period should not worry you all the time. Sometimes our internal system undergoes major changes that result in an imbalanced cycle. We do suggest you consult a doctor in case of uncertainty.
