PGP and talking to doctor

When should you talk to your doctor about pelvic girdle pain? I’ve brought it up the past few appointments and they brush it off like I’m overreacting. I can hardly walk or even stand at this point and I was in tears about an hour ago from the pain. I don’t do anything anymore, I literally lay down in bed or the couch all fricken day because it hurts to move at all. I go back and forth to pee and then lay back down. I’m getting really depressed about it. Especially since I’m 36 weeks Sunday and baby is transverse too. I’m just so upset and sore and my doctor just won’t take me seriously. She says it’s normal or smirks or whatever so I just let it go because I don’t want to sound annoying or like I’m just complaining but fuck...idk what to do anymore 😩
