An ultrasound showed I was pregnant with twins but one sack empty, the other had a fetus with heartbeat 7 km in length.2 weeks later another ultrasound showed 2 empty sacks.I had tablets inserted and passed the sacks.Yesterday I passed a 51mm fetus in its sack. The fetus is formed.What do I do?I have no pain, but where did fetus come from?Help!
