Pain!

Had to take femara this past month and I'm pretty sure I ovulated the wkd of the 20th (didn't use OPKs but my breasts were tender for a couple of days). My problem is the past couple of times the hubs and I have had sex (including the wkd I think I o'd), it's a bit painful... kind of crampy?? This happened once last August and I ended up being pregnant. Unfortunately, I miscarried. Has anyone experienced this before?

I'm also 3 days late.
