delayed menstruation

The female menstrual cycle is generally 28 to 30 days. Being 7 days earlier or later is still within the normal range, and cycle length varies from person to person. However, if menstruation has not occurred after more than 7 days, it is considered delayed menstruation. Delayed menstruation mainly requires consideration of two causes: first, pregnancy, and second, menstrual irregularities. If there is sexual activity and condom contraception is used without rupture or leakage, the possibility of pregnancy is low. The self-test rate of early pregnancy test strips is relatively low; close observation is recommended. If the menstrual period is extended by more than 10 days, blood HCG or ultrasound examination can be performed at the hospital to determine whether pregnancy has occurred. At the same time, abortion surgery or intrauterine surgery, endocrine disorders, and premature ovarian failure can also cause delayed menstruation. When women suffer from endometritis, endometriosis, cervicitis, salpingitis, ovarian dysfunction, or endocrine system disorders, varying degrees of menstrual abnormalities will occur.
