I'm really close to the same due date as you and having the same things happening..I ended up getting a pregnancy pillow which I like but it makes it hard getting in and out of bed!! Try to put a pillow between your knees if you can to alleviate the pain, hopefully this helps!
I put a pillow underneath the hip that I'm laying on I went and bought a memory pillow and its so soft it doesn't take the pain away completely but it does help a lot! I got mine at walmart
