Back Pain

I'm 17+5 and for the past few days I've been having really bad back pain, to the point I can't walk properly. It starts in my lower back near my spine and shoots into my hips. It's also interfering with my sleep because I can not find a position lying down that doesn't make the pain worse. Nothing I have tried so far has helped, so I'm reaching out to you ladies.

He any of you ever experienced something like this, and what did you do that helped the pain?
