Cycle MIA

Hi, I haven’t had a cycle since the beginning of May 2019 (shot). May 2018 is when I started birth control for 3 months then stopped & didn’t start back until October in college (patch) ...then stopped again. It was irregular for a while but I thought it was getting back in line ...however , I missed my cycle in June. I had sex in May protected and again in June but I still don’t see my cycle ...or symptoms of a cycle ...
