POSSITVE OPK today 2/18 CYCLE DAY 20

Laa
Okay so didn't expect this I had to rewrite I am actually ovulating today I was wondering why I was feeling crampy and sensitive in boob's for a couple days now. I am 14days away from Af is a shock thought I'd ovulate earlier?? because my Af was on 1/30 ) but anywho so today is ovulation day 2/18 I was confused cause I ovulated early last cycle?! also using other app because of more detailed accuracy I put ovulation day and gave me my new fertile window when I updated it today
