If a woman with regular menstruation does not see fetal heartbeat or buds at 8 weeks of pregnancy, she needs to undergo ultrasound to determine the development and to measure the blood HCG value. If these tests show that the fetus is not well developed, she needs to terminate the pregnancy according to the doctor’s instructions. In addition, it is necessary to go to the hospital to determine whether the number of weeks of pregnancy is correct. For women with regular menstruation, the intrauterine gestational sac can be seen around 6 weeks after menopause, and the fetal heart can be seen around 7 weeks. At this time, ultrasound should be used to monitor the development of the fetus, and at the same time, the blood HCG value should be measured, if the ultrasound indicates that the fetus has stopped developing, and at the same time, the blood HCG value is on the low side, the fetus is considered to be underdeveloped, and the pregnancy should be terminated as soon as possible. Some pregnant women have irregular menstruation or long cycles, and the actual number of weeks of pregnancy does not reach 8 weeks, at this time there is no fetal heartbeat or buds, which should be normal. Pregnant women are advised to check blood HCG and progesterone for professional judgment. It is recommended that women with regular menstruation should terminate the pregnancy in time if the pregnancy has been confirmed but the fetal heart and buds are still not seen at 8 weeks of gestation, considering that the fetus is underdeveloped, in order to avoid adverse consequences such as vaginal bleeding, endometritis, and so on. If there is any discomfort, consult a doctor promptly.
