Severe itching vagina and butt?!

Natasha
For the last 3 weeks My vagina and butt has been itching and burning badly.  I'm losing sleep and have tried everything over the counter. Regular docs won't see me bc I'm preggers but obgyn offices keep making me wait 3 weeks or longer! Even though I've explained my situation. They say it's not serious enough to see me sooner but maybe I should go to ER??!?! Anyone else having this?
