Been spot 4, 2 weeks doc took blood nd said levels are high why am i still spotting in my 1st tri nd doc said look lik a healthy pregnancy why am i spot?

It could be that the: Implantation of the fertilized egg is not stable. Get some bed rest, avoid sex for now until bleeding stops . Let's hope and pray that pregnancy will be a success!

Implantation: You can have bleeding early in pregnancy from implantation, but you can also have bleeding from the placental edge as it grows; also, you can have small vessels in the cervix that cause some bleeding on occasion.
