If you usually have your period once a month and you haven’t had it for 36 days, you should first check if you are pregnant by taking a urine test. If you feel that the early pregnancy test is not working or not allowed, you can come to the hospital to have your blood drawn to determine if you are pregnant. Delayed menstruation for 36 days is equivalent to 6 days of menopause, it is not necessarily pregnancy, there are many reasons, such as ovarian cysts, ovaries are polycystic ovary syndrome, this time menstruation can be delayed, so not 36 days without menstruation is pregnancy. Therefore, if you don’t have a period for 36 days, you should go to the hospital to check your urine and blood, especially blood HCG, or even ultrasound to determine if your uterus or ovaries are abnormal.
