I'm fairly certain. Not officially ruling myself out for the month, but I am feeling cranky, hostile, and mildly crampy in the abdomen, and that usually means PMS for me.
I'm okay with it. My honeymoon in late June/July is going to involve the opportunity to drink lots of great Italian wine, so if I am not pregnant before then, I feel like it's okay, I have something to look forward to.
Anyway, I can't beat myself up too much about it. We did everything *right* this month. Just not our month, I'm thinking.
