Hi, So very sorry for your loss. I also had irregular periods after my m/c. This is very normal as your hormones need to complete;y reset themselves and your lining needs to recover. I didnt get AF for about 7 weeks after my m/c and I also got bfn's all the time. It was just late because my body was recovering. Now everything is back to normal and I have regular AF again. Once they become regular again, it should be ok to TTC again. Good luck for the future, I hope they return to normal again soon.
