I don't want to sound like I'm being negative, because of course I wish you the very best in your TTC journey, but please be aware that you might not actually be ovulating. There's no harm in trying, so it's not like I'm telling you to stop. But I just wanted to alert you to the fact that fairly frequently the OPKs will give you false information this soon after an m/c. Your hormones are all over the place and a false reading wouldn't be unusual at this point. I guess the only reason why I'm even bothering to type this is if you don't get pregnant this month, I don't want you to feel all that disappointed, since it really is too soon for most women to be ovulating. Of course, having said that, there are definitely SOME people who have ovulated and were able to get pregnant within 2 weeks, but it's pretty unusual.
anyway, good luck!
