OPK question!!

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 gunna post this here because you guys are the only ones that answer me!! So anyway, when I use OPKs it's really weird.. I never get a second line until it's positive, I know there is suppose to be a second line always but not for me I guess. Then I took these today as AF ended (early might I add) and I got this.. Again I never see two lines until positive.. Can I be about to ovulate already?!?! For reference I'll post last month's cycle as well (last picture) so you can see what I mean by no lines. Thank you in advance!
