No periods TTC

Shelby

Long story short I do not have periods and have always been irregular unless I’m on birth control. I haven’t been on birth control since March and my SO and I have been TTC. How am I supposed to know when I ovulate or if I am even fertile? I’ve mentioned concerns to my OBGYN but she never seems concerned. I’ve started considering changing doctors. Wanted to know if you guys had any tips or tricks or similar stories!
