I'm pretty sure that I actually Oed late in the day on CD 15. My +OPK was at 6am (blaring), but negative when I did it again later in the afternoon. My watery CM also disapeared as of CD 16.
Obviously based on our BD timing, I'm hoping for CD 15. BUT when I put in "fake temps" for the next 2 days, FF puts my O date as CD 16.
Knit-picking, I know.....but I always worry about our BD timing and I'm hoping that our AM BD on CD 15 was good enough to get my bfp this cycle.
Do you think I Oed on CD 15 or 16? You can tell me the truth too, don't worry about hurting my feelings. lol.
