The TWW

Brandi • My name is Brandi and my fiancé`s name is Joe. I`m 23 he`s 25. TTC baby #1. I`m a hair stylist and he`s in flooring.
Well I'm officially out of my fertile window and getting negative clear blue OPKs (after 2 days of positives) I ovulated early, CD11. I read that not matter when you ovulate it marks the middle of your cycle. Is this true? Like AF would be due 11 days after ovulating? When should I start testing?
