A late or missed period may occur for many reasons other than pregnancy. Natural causes can run from lopsided hormonal characteristics to genuine ailments.

As your body experiences the change, your cycle can end up unpredictable. A woman’s menstrual cycle is generally around 28 days. However, this duration can also range from 21-35 days. If you do not get your periods within this period, it could be due to one of the following reasons.


Women with dietary issues like anorexia nervosa or bulimia may miss their periods. Your body capacities and ovulation can be changed even if you weigh 10 percent beneath what is viewed as a healthy range. An increase in your weight can restore your menstrual cycle. Additionally, women who take an interest in outdoor exercises like long-distance races may miss their periods too.

When you go on or off contraception, your period cycle also changes. This is due to the hormone estrogen and progestin in anti-conception medication pills, which prevents your ovaries from discharging eggs. It can take as long as a half a year for your cycle to regularise again in the wake of ceasing the pill. Different types of contraceptives that are embedded or infused can cause missed periods too.

When Pregnancy Is Not The Reason
Serious Ailments

Ailments such as diabetes and celiac infection can further influence your menstrual cycle. Changes in glucose are connected to hormonal changes, so even though it is uncommon, ineffectively controlled diabetes could make your period unpredictable. The celiac illness causes irritation that can harm your small intestines, which may keep your body from absorbing essential nutrients leading to late or missed periods.

Early Perimenopause

Most women hit menopause between age 45 and 55. Some women who begin to show side effects around age 40 or before are considered to have early perimenopause. It implies that their egg supply is slowing down.

Thyroid Issues

An overactive or underactive thyroid gland could also be the reason for late or missed periods. The thyroid gland controls your body’s digestion so that hormone levels can be influenced too. However, thyroid issues can be treated with medication, and your period will probably come back to normal after the treatment.
