Had a natural miscarriage that started on April 16 and lasted five days. My HCG dropped quickly according to my doctor, last week it was down to 8 on Wednesday. After the miscarriage I saw my doc and she gave us the green light and said nonfessom we should wait or have any issues. Since then we have been BDing regularly (every day or every other) and since April 26 I have been using OPKs once a day between 4-5pm. I occasionally would get a darker line but nothing considered positive. Yesterday I had some intense cramping, they'd come suddenly and then taper off. Several times over the day. Felt similar to the implantation cramps from the first pregnancy. If I count first day of the miscarriage as CD1 I would've ovulated around the weekend of the 29-30th. Could the cramps have been implantation?? I did another OPK today and barely there line. Thinking maybe I missed my surge? Dying to test but know it's pointless for another two weeks. The wait is torture!
