the worst possibilities here are miscarriage and ectopic pregnancy. you may also be having what is known as a threatened miscarriage, which basically means that there is something posing a threat to the baby that may heal itself or result in a miscarriage. i had the latter this pregnancy. all is well now and am 30 1/2 weeks. the best outcome is that you're just bleeding ( which does happen ) and baby will be fine. i wish you the best of luck.
hi well im 8 weeks pg and i have heavy bleeding on the 5th week and i was soooo sacred and they called it threatened miscarriage and it was dark red and it was outside of my cervix so it was ok, and now i havent bleeded since, but i used to have like brown discharge or old blood i dnt know but i think ull be ok, maybe ur levels are low cause u just started ur pregnancy, but just try staying off ur feet and dont pick up nothing heavy!
