Yay!!! I'm so happy to be able to finally post here!
Just got my BFP this morning, although I'm not positive when I O'd--FF says C 13, I think CD 10. Either way, it was very early for me. It was completely in God's control, though, because on CD 11 I went out of town and was gone for 4 days, which, if I had O'd at my usual time we would have missed it. Looks like we didn't.
Tentative EDD is April 14, but could be anywhere within that week, I think.
I think I'm going to go out and get a digital test just so I can see the word "pregnant".
