Generally at this time, an ultrasound examination may show fetal heartbeat, fetal buds, etc., which can roughly determine the development of the embryo. The medical rule is that 1 month is 4 weeks. If a pregnant woman is 7 weeks pregnant at this time, then it suggests that she is less than 2 months pregnant. Usually at this time, when you go to the doctor for ultrasound examination, there will be the appearance of fetal buds, and some pregnant women will also appear fetal heart. Therefore, generally 7 weeks pregnant can go to the hospital for ultrasound examination, by determining whether the size of the gestational sac and the number of days of menopause, to determine the development of the embryo. At 7 weeks of pregnancy, if there is no vaginal bleeding or abdominal pain, and the ultrasound indicates the presence of fetal heart and buds, most of the time the embryo is well developed. If there is vaginal bleeding, abdominal pain, etc., most of the cases are considered to have preterm miscarriage, and it is recommended to consult a doctor for a clear diagnosis before treatment.
