What to do

So back story I’m on Lupron depot for my endometriosis so I got my period which I wasn’t supposed to and it was 12 days early so now I discovered my vagina seems swollen and burns really bad I’ve been told to call my obgyn but I keep cramping up so bad I don’t know what to do it feels like I have endometriosis all over again that’s how bad the pain and bleeding is
