Frustrating long cycles

So I had the methotrexate shot and finally was able to start trying again about three months ago. But ever since I've had the most unusual long cycles. Usually I'm 28 days like clockwork. But each of my last two cycles were over 50 days. I am afraid I'm not ovulating. I'm definitely not pregnant 😭. Anyone have similar issues? Should I be contacting a fertility specialist or am I jumping the gun too soon? I'm just so anxious and want that BFP. It doesn't help everyone around me is getting pregnant !!!

Trying to stay positive but dang is it hard!!!
