I am currently 7 week pregnant and have now had bleeding twice not like spotting but like a period. This last time is was like a faucet had been turned on and I passed some clots. I have had several ultra sounds and they say the baby is fine, and I am fine. I saw the heartbeats myself. I can't seem to get an answer for the bleeding. It seems to be coming about the time my period would. Has anyone else had "periods" while pregnant? I am just worried about why it is happening. My doctor has put me on progesterone pills saying he thinks I have a uterus resistant to stretching. Has anyone heard of this?
