New to BBT

Me

Hi Ladies,

I'm 11 DPO and my temp is the highest it has been (98.5) since the beginning of my cycle. I definitely ovulated per the bbt and opk. AF is due in 3 days...if she is on the way, when will I see the temp drop? The day before? That morning? I just want to know what I'm in for, LOL. THANKS!
