Multiple positive ovulation tests

I’m currently 11 months post partum and still haven’t gotten my period. I stopped breastfeeding around 7.5 months. It also took using fertility meds to get pregnant as I have PCOS. We are trying again because we know it could take years again to get pregnant. I’ve been testing for ovulation since Friday (top strip) and it has gotten darker, but even today (bottom strip) it does not look to be getting lighter. When could I possibly have ovulated? Or am I even ovulating yet?
