You don't HAVE to BD tonight, but I think if you want to feel as calm as possible about doing everything you could do, then maybe you should

FF isn't the end-all-be-all (although it is pretty smart!). If you haven't already read my other post about you and Melissa and me, go read it

THIS IS OUR MONTH. And whoever else wants to head over to April '12 is more than welcome of course
PS - Just adding... I always O either 1 or 2 days after my + OPK. Temping drives me crazy, I've never gotten pregnant during a temping cycle, so I quit. I trust my OPKs just fine. Ideally I start having regular (every other night or so) sex with DH when I first start seeing EWCM, but it didn't go that way this cycle for me. Have you always had irregular cycles? I thought you always used to O at the same time?
