HI! If you were my patient, I would have you in immediately for an ultrasound. It is not normal to bleed that much. The ultrasound will tell you what is going on. I suspect a subchorionic hematoma ( a bleed between the baby's sac and the wall of the uterus). Sometimes these heal up and go away just like a bruise, and other times they cause a miscarriage, but you should definitely be checked!
Good luck!

I wouldnt think that any HEAVY bleeding would be good during pregnancy. I have heard of women who continue to have periods during pregnancy, however I cant imagine it being a heavy flow. Do you have any pain or cramping? I would make sure to check with your Dr. asap!
