Patient's question:
I got married last year. Recently, I've been experiencing lower abdominal pain, especially during my period. I'm very worried about it affecting fertility, and I'm also extremely sensitive to cold and coldness. How big does the gestational sac need to be to see the fetal pole and heartbeat?Doctor's answer:
Hello, during embryonic development, a gestational sac forms between 30-40 days, a blastocyst forms between 40-50 days, and a fetal heartbeat develops between 50-60 days. In your case, it may be threatened miscarriage. Threatened miscarriage refers to a condition in early pregnancy where there is slight vaginal bleeding that comes and goes, accompanied by mild lower abdominal pain and lower back pain. It may lead to miscarriage. It is recommended to undergo an ultrasound examination first, and if necessary, receive treatment to prevent miscarriage.
