Does your hcg levels have to be 0 in order to get pregnant again after a natural miscarriage? My OB is really an ass and she’s definitely not keeping up with my levels so I have no clue what they are or if it even still in my system. I miscarried at 7 weeks . I passed all the tissue and sac on last week . My bleeding has stopped since 5 days ago and I’ve been having unprotected sex every since then . How long did it took you ladies to get pregnant after a miscarriage?
