How do I track my ovulation with birth control ?

Shanelll

I am currently being put back on bc because of the seriousness of my pcos. I haven’t had a period in months and I am trying to conceive. I’m honestly so confused and distraught I need suggestions because my gyn just isn’t giving me the information or education I need. 😩 my doctor is putting me back on bc to try to “trick” my body into having a period.
