Birth control shot and headaches

I've been on Depo Provera since 2023 and for the first few months it helped and stopped my period as I am transgender, But I've been dealing with a great amount of discharge that has been severely effecting my daily life. Warmth makes it worse and even though I'm a incomplete Paraplegic, it constantly feels like there's liquid coming out of me. When I do get my periods sometimes it's heavy spotting and whenever I use a tampon there's never any blood, but when I don't use a tampon then there is a massive amount of blood. I was once bleeding everyday for a month straight maybe even longer. I was never told any of the side effects besides it stopping my period.

My right breast has swelling so bad that it have my body aching this is different from just regular breast swelling from had a baby it honestly got me a lil scared cuz it making me weak have any one had this happen while on b.c

Been on it for 4 years, I’ve gained 50lbs from it, went up 4 cup sizes, I throw up so much I have to take meds to keep it down, my hair is ALWAYS falling out, my body is always aching and I haven’t had a single period since I started it. Not to mention I get dizzy, sweat non stop, and have trouble falling asleep and staying asleep now.
