My af returned 25 days after my ERPC. It was right on time - as though I'd never been pregnant - 16 weeks to the day since the last one (I was 12 weeks along when MMC was discovered). The next one was 27 days later. So pretty much right off. I didn't ovulate first cycle as I as bleeding the whole way through to af and then for a week after. I did ovulate that cycle (according to opk's) but no bfp - which I wasn't that suprised about as scan showed retained products. I'm hoping last af cleared that out but I'm not overly optimistic.
I feel out already this month.
I feel quite optimistic for you. My cycles have been really long since my mc, but they were long before anyway. Seems like your body has snapped back to normal already thats great. I didnt ovulate 1st cycle either but i did the last cycle, though i had positive opks for 5 days in a row. I believe i was meant to ovulate on a tuesday but due to stress etc i didnt until saturday, thats when I felt the OV pains and AF came exactly 14 days after. I have a feeling that MAY is gonna be your month
