So as you ladies know I was experiencing heavy cramping and bleeding yesterday.. Did ultrasound found nothing no sac or baby. My calculations I should be 6weeks today. Had a pelvic exam cervix is still closed though. Today my cramps are gone but I'm still heavy a "period". My levels on 9/12 was 41 when they did beta. My doctor called just now and said my level was 181 yesterday. She's having me come in tomorrow to redraw the beta. Prayers and any insight as if you think I'll be ok , experience etc.. Thank you
