Advice needed, dental pain

So I’m 35wks pregnant and I have a tooth that really needs pulled. They did a partial root extraction (it’s my farther back molar) a couple years ago and the pain subsided but now it’s back and I need to get it pulled badly. The pain is killing me, literally and I know I need to go to the dentist but they can’t see me for 6 weeks. Does anyone have any advice or personal experience with this?
