Hello, I've had a previous tubal and chemical and finally after 3 years of trying I'm pregnant again. I've had early scans to monitor me due to my previous history and at 5wks we saw ges sack and yolk sac in the uterus. I'm now 6wks and had another ultrasound yesterday which showed a tiny flickering heartbeat. However since I've come home from the hospital I'm having slight cramps and light brown/pinky spotting when I wipe. It isn't enough to touch a pad but I'm absolutely terrified that after seeing the hb something is going to go wrong.
