Help!

Rebecca • First baby❤️

So a couple nights ago I started having bad back pain and it hasn’t let up like it has in the past I’m currently 39 weeks pregnant. It’s so bad to the point I’m crying laying in bed because nothing helps and when I walk there a sharp pain in my vagina area (which I got sometimes before) anything to help?? I’m absolutely miserable anybody know what could be causing it out of nowhere?
