Not ovulating monthly?

Sky

Sorry ahead of time is this isn’t the appropriate group. In late May I stopped taking my birth control, a few weeks later I ovulated and two weeks after that I had my first normal period. Assuming I was back on track, I started taking OPKs about five days after my period ended, the first time I tested the line was very light, second day I tested it was a little darker but definitely still negative, and I continued taking test everyday and they just got lighter and lighter until there was pretty much nothing there. So my question is, is it a normal thing to not ovulate every month?? Or is it maybe because my period isn’t regulated since stopping birth control even though it seemed my cycle went back to normal? I’m just super confused and upset because we were ready to BD this month and hope for the best but instead I didn’t even get a positive opk, has anyone ever had this happen to them?
