Has anyone conceived with BDing only at O-2?

I am not even asking what the sex of your baby was. Just if you conceived. You may have read it in my other posts but I thought I had a positive OPK on Monday so we BD'ed that night around 11 pm. Peed on another OPK yesterday around 2 pm and it was obviously darker. So I assume I will O today. So it will be about 48 hours since we BD'ed, right? I know you can O between 12-36 hours after a positive OPK. This is CD15.

We were unable to BD last night. I have had more EWCM the days leading up and now my CM is wet but still there. I did take a Zyrtec the last two days so I don't know if it dried me up closer to my cervix. I am hoping some spermies stayed alive up there!

yes, I conceived 3 of my 5 2 days before O or even more and the other one I just don't know when I Oed so it could have been true for him too.
