Hello doctor! I am 6 weeks pregnant, I went to the doctor and was diagnosed with a fetal growth arrest because there was no fetal heartbeat, then I waited for a week and had abdominal pain and bleeding. I went to the hospital and the placenta had come out, the ultrasound doctor said there was nothing left but fluid and blood. That means I had a miscarriage, but 2 days later I had severe abdominal pain and the fetus was gone, the fetus was as small as a baby's little finger. So I would like to ask the doctor: "Why does a 6-week-old fetus stop developing and have vaginal bleeding but still have the shape of a fetus?" If I was still pregnant when the placenta came out, would the fetus still be alive? Thank you doctor for your advice!
