Can somebody dumb down the menstrual cycle for me?

Sara

I’ve been doing my own research but it’s not helping me understand what is going on in my body? I’ve never paid attention because I’ve always been on BC and I’ve hardly ever had a period.

I get acne, super bitchy and depressed before and during period. Coming off of it, I’m horny. What hormones are these? Estrogen? Progesterone? I don’t ovulate coming off of my period right? Or do I? Can’t believe I’m 27 and just now really paying attention to my body.
