Still no BFP?

I posted A couple days ago (new to bbt and ttc), but was wondering what people thought...

Facts: stopped pills in Jan- before starting pills I was irregular (about 10 years of pills)- have PCOS- last luteal phase was 15 days, but temps were all over- slightly sore nipples (not breasts)- lower abdomen feels “tight”

Just wondering what “more experienced” eyes see, notice, and suggest :) THANKS!
