TTC after bc, need some help

Hi, I've got some issues right now and I need some help. I've been on bc pills for 2 years and I've stopped taking them July this year, since then me and my husband have been TTC, but so far we had no luck. Has any of you ladies been on bc pills and then TTC? How long did it take to get your BFP? My cycles are longer than when I was on bc, but AF always comes on time. My obgyn told me I may have PCO but my endocrinology tests are fine. So right now I'm stuck, I used opks but gave up this month because I started to get upset when AF came.
