Bone pain

I'm in my 27th week and I really started noticing pain (since week 26) in the front of my vagina. The pain literally feels like bones are going to snap. I really notice it at night when switching positions or when I stand or walk after sitting for a bit. It's not round ligament pain (I have had that - unless it's a different ligament maybe) and sometimes it's accompanied with pressure at the base of my vagina like a foot or arm is going to pop out. Any ideas?
