I’ve been on my period for 157 days no

Hi everyone I am 21 years old and I’ve been bleeding for 157 days straight. I have gotten blood work and a Pap smear they both came back normal, I’m not even anemic. I am waiting to get an ultrasound. We believe it is caused by my antidepressants (Zoloft, seroquel, and oxycarbezine). I have been on them for years now and have had my period start/stop while taking them. I decided to stop taking my medicines for 9 months and I didn’t get my period those entire 9 months. once I started the medicines again my period came right back and went back to normal.

However, about 6 months ago I lost health insurance for about a month so I couldn’t take my medicines because I ran out. i once again didn’t get my period while I stopped taking it. Once I started again about a month later I got my period and I have been on it ever since. I got my period on February 1st and it is now July 7th and I’ve been bleeding everyday since. Sometimes it’s a lot others it isn’t.

I was prescribed Provera by two gynecologists to stop my bleeding. it’s a 2.5mg dose a day for 10 days. I am nervous to take it because when you search it, it says not to take it if you have undiagnosed vaginal bleeding. Should I still take it? I think it must be safe if two gynos prescribed me it. Any advice is appreciated! Thank you
