I had a mc on 12/5/2017. Bled for 5/6 days like a period. Had a positive opk on 12/29 (same day i got my hcg blood results back which showed negative) kept testing because i wanted to make sure. I’ve had no period. These past few days i had been having cramps on pelvic area and lower back. If i go by FF I’m around 11dpo. And i got a positive!!! I’m sure it isn’t leftover hcg!! Had to book my appt and won’t go in till last days of February. I’m worried of a mc happening again since i have a bicornuate uterus.
