ovulation, cycle questions

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.
So I'm out of my fertile window and officially getting negative clear blue OPKs (had 2 days of positives) I ovulated very early, CD11. I did a look google searching and read that no matter when you ovulate it marks the middle of your cycle. Is this true? So my cycle would only be 21 days? When should I start testing?!
