I talked to the dr. and she told me to stay in bed with my feet up and drink lots of water. She said that this is pretty common. Sometimes the placenta opens a blood vessel while it's growing or some women just bleed during the first trimester. I've had a few clots, but they were about the size of a dime. The dr said that unless it gets to the size of a quarter, everything still looks ok to her. My cramping has stopped after being in bed for the last 2 hours and my bleeding seems to be slowing down. I'm in bed on my back with my laptop. I'm feeling hopeful. My u/s is at 7:30 est tomorrow. I'll update as soon as I get home.
DH also found some forums and there were many women who said they had AF bleeding and clots during the 1st trimester and went on to have healthy babies.
