Possible Cyst Rupture?

So I’ve been on my period for almost a month now. after starting a birth control to try to help with my PCOS. But all of a sudden my period has gotten heavier and my cramps are so bad that they’re paralyzing and make me nauseous.

Went to UTC and all they did was treat the nausea.

What can I do to help the pain? Midol isn’t working.

Is the pain so bad bc A cyst is rupturing?
