My period has not come for 20 days.

In fact, as long as a woman's menstruation is delayed within seven days, it is normal. But some women find that their menstruation has not come for 20 days, then we need to pay attention. If you have had sex before, you must see a doctor immediately to find out the reason. Let's discuss what happened when the menstruation has not come for 20 days?

Causes of delayed menstruation

1. Pregnancy causes delayed menstruation. If a woman's menstrual cycle has always been normal, but suddenly it is delayed for a month, then we can use a pregnancy test strip to test it, and then see a doctor for further examination.

2. The side effects of therapeutic drugs cause delayed menstruation. Some people have the habit of taking emergency contraception for a long time, which will cause endocrine imbalance. After endocrine imbalance, menstruation will naturally be imbalanced.

3. Uterine and ovarian factors cause delayed menstruation. Polycystic ovary syndrome and ovarian aging can actually cause delayed menstruation in women. If we encounter abnormal conditions, we must take some measures to treat them in time.

4. Surgical treatment causes delayed menstruation. Some people may have had medical abortion or intrauterine surgery, which can also damage the uterus. Menstruation may also be delayed, but in this case ovulation can usually be restored 22 days after surgery.

5. Psychological disorders such as anxiety, stress, and changes in the natural environment may cause menstrual period. Women will feel uneasy and have breast pain, but these conditions generally do not require treatment.

6. The most common clinical diseases are tumors, hypothyroidism and other chronic diseases, which are often caused by malnutrition and can also lead to delayed menstruation.

7. Excessive dieting methods are used to lose weight. This will cause a lot of body fat and protein to be consumed, leading to the obstruction of estrogen production, which will also affect menstruation.
