Pregnant for more than 40 days, the fetus is small, what should I do?

Patient's question:

No

Doctor's answer:

Generally, a gestational sac can be observed in ultrasound at 4-5 weeks of pregnancy, and a fetal bud emerges by 6 weeks. By 7-8 weeks, a heartbeat and blood flow signal can be detected. At 40 days of pregnancy, the normal size of a gestational sac is about 1 cm. It is recommended to increase nutrition, rest, and avoid sexual intercourse.
