MrsG - crazy OPK stuff been happening with you Hun. Weird! I must admit I think I've had a few cycles where I got three days in a row of pos OPKs and it totally flips you out. Actually two cycles ago when I got a BFP I had gotten pos OPKs 5 days in a row, and FF marked me as having Oed on CD 15, which was slap bang in the middle of the five days of Pos OPKs. So O was on 3rd day of Pos OPK. I don't know why it happened like that...maybe you have an initial surge and the egg is having trouble being released and keeps trying so you keep getting a surge until it's released? I don't know. Good luck Hun.
