I'm posting this in case it might help reduce someone's anxiety if in the same situation. I have had no spotting since 5 wks (9+3 days today) and back then it was just pink. Anyway, today I had quite a bit of cramping and then clotting and bleeding.  I prepared for the worst since I had an angel in January. My doctor said to go to the ER. I went knowing they couldn't do anything but figured I wouldn't be able to sleep not knowing. Good news, got an ultrasound, all appears to be well with a heartbeat of 177. So grateful! Prayers to anyone in a similar situation.
