How to help with pain?

Elizabet
Any advice would be Greatly appreciated. I'm 32 weeks and For the past two days I've been having pains, like not around Ligament pains, or pressure. But pain. It starts like underneath my belly, or the top of my vagina and radiates to the top of my stomach. I couldn't sleep, it would just hit me and then go away. It's been happening all day, the more I walk, the more it happens, I feel like she's pushing on my vagina and gonna come out. I've been drinking water to try and help it but nothing works. I keep feeling like I have to go to the bathroom but nothing comes out. How can I make this pain go away or at least better so I can sleep at night?
