NO WAY 😱

"AF" last for 2 1/2 weeks... I quote it because AF has been late before but NEVER lasted more than 7 days. And it wasn't even the usually AF. At first it was light pink spotting then bright red for 3 days and then light spotting again. I didn't feel any cramps or anything. Well I got off it yesterday finally and today I decided to test... OPK is so close to positive or even positive 😱 what is going on ?!
