My Doctor doesnt seem concerned but it doesnt seem right. im 6 weeks and 4 days and there was no fetal pull. i was bleeding on Sunday and now im just spotting brown but they ruled out ectopic pregnancy and it doesnt seem like im having a miscarriage, my bhcg levels are rising every 48 hours and my sac is there but it doesnt look right they said. She believes i can keep this pregnancy but im so scared because they are talking to me about losing him/her.
