am 5.6 weeks pregnant. However, I had brown bleeding, the next morning red bleeding, no abdominal pain. I had a transvaginal ultrasound and was diagnosed with a deformed, uneven gestational sac, no fetal heartbeat. Therefore, the doctor concluded that the fetus had stopped developing and prescribed me to take abortion pills tomorrow. Doctor, can you tell me, is it dangerous for a 6-week-old fetus to have no heartbeat and a deformed gestational sac?
