I had a loss in July. Mine was natural though, not D&C, and my first period was very light. My second period though was absolutely the worst. It was after that when we considered ttc again because I didn't want another period from hell. This is our first cycle ttc since my mmc so I'm hoping for a sticky bean this time. It is good that you waited until your first period because it takes a while for your hormones to get out of your system and thus would give you positive opks when you're really not ovulating. Also, I've read that sometimes the body doesn't ovulate the first cycle between miscarriage and AF. I know how much torture the wait is though and can only wish you the best!
