The best time to take an early pregnancy test is when a woman of childbearing age has a normal sex life and is not experiencing lower abdominal pain or vaginal bleeding 7 days after her period has been postponed, i.e. about 37 days after menopause. When menopause 37 days, because the body’s chorionic gonadotropin level has been higher, urine pregnancy test will generally appear two red bars, and during this period to do gynecological ultrasound, most can see the uterine cavity with the appearance of the gestational sac and the primitive heart tube beating, can be diagnosed as normal intrauterine pregnancy. If a woman’s menopause is shorter, such as in the menopause within five weeks, that is, within 35 days of menopause, due to the body’s hormone levels rise lower, and do gynecological ultrasound, the uterine cavity can not be seen within the growth of the gestational sac, it is not easy to make a correct diagnosis, may appear to have an error, and need to be reviewed again in order to make a clear diagnosis. In short, women’s early pregnancy test time is generally around 42 days after menopause, if there is a delay in menstruation or the growth and development of the fertilized egg slower, you can prolong the detection of early pregnancy time.
