What is wrong with me

This January I got the depo shot. For about 2 months I had no period. And then in March I started my period and it lasted 2 weeks. Ever since then my period was irregular as hell. I’d have my period for like 3 days then 2 days I’d be period free then start up again and for the next 5 days I’m on it and then 1 day period free. It got so bad to the point where I started having mental breakdowns because of it. My doctor put me on the pill 1 month ago and it just got way worse and it about to be 3 weeks with my period. Also every time I orgasm I bleed. I have an appointment with a gynecologist now and an ultrasound. Has anyone gone through this or know what could be wrong?
