About 35 days after pregnancy, you will usually find that your period has stopped coming. Pregnancy is counted from the first day of the last menstrual period. If you find that your menstrual period has been delayed for a week and still does not come, and you have had intercourse that month, you can test with an early morning pregnancy test paper or go to the hospital for blood tests for HCG and progesterone, to confirm whether you are pregnant or not. In fact, once you are pregnant, you will stop menstruating. Menopause is the earliest manifestation of pregnancy, and you will stop menstruating throughout the entire pregnancy, and the time for menstruation to come back after delivery varies from person to person, with some women needing 3-4 months, and some more than a year. Pregnancy will definitely stop menstruation, but stopping menstruation is not necessarily pregnancy. So if you notice that your period has stopped, you can take an early pregnancy test to determine if you are pregnant. If you are not pregnant, you should actively do other tests to check the cause.
