Reasons for delayed menstruation for 16 days

The phenomenon of delayed menstruation is very common in life, but it is normal for menstruation to be delayed within ten days. Therefore, when menstruation is delayed for 16 days, it must be rectified in time. If you have had sex during this period, you can buy a pregnancy test stick to test whether you are pregnant. Because the reasons for delayed menstruation are not only pregnancy, but also related to physical factors, so what is the reason for delayed menstruation for 16 days?

What are the reasons why menstruation is delayed for 16 days? The menstrual cycle is generally 28 to 30 days. About 7 days earlier or later is still within the normal range, and the length of the cycle varies from person to person. But if it exceeds this time, women with normal menstruation will definitely worry. The reasons why menstruation has not come for 16 days can be divided into the following four situations:

1. Pregnancy: You can use the "Early Pregnancy Test Strip" to test urine 7 days after your period is delayed. If the result is positive, you are very likely to be pregnant. If the result is negative, the opposite is true. But if you are pregnant, there will be other symptoms such as nausea, breast tenderness, etc. Of course, the last resort is to go to the hospital for an ultrasound examination.

2. Side effects of drugs: For example, endocrine disorders after long-term use of contraceptives can also cause menstruation to be delayed by 16 days.

3. Caused by surgery: For example, intrauterine surgery may cause cervical adhesions and result in menstrual blood stasis, thus delaying menstruation.

4. Others: psychological factors such as mental tension, stress, environmental changes, and some diseases that affect endocrine system. Can cause delayed menstruation.

The above are the reasons why "menstruation is delayed by 16 days and has not come yet". If menstruation is delayed by 16 days only 1-2 times occasionally and there are no other accompanying symptoms, it does not fall into the category of menstrual disorders. When the interval between menstrual cycles is more than 35 days, it is called oligomenorrhea, and when menstruation stops for more than 3 menstrual cycles, it is called amenorrhea. The absence of ovulation after amenorrhea can also lead to problems such as osteoporosis and endometrial hyperplasia, which must be taken seriously. You should go to the hospital immediately for a comprehensive examination.
