Contractions??

Someone help please? So I've been extremely stressed and hormonal and crying for the past two days, and my stomach has just been uncomfortable, but that'sexpecyed at 35w 2d. Anyways, I get it together finally and husband and I had sex twice today back to back, and I'm feeling some serious pain in my back and sides and kind of my bikini line area? Pressure like I need to pop but can't. I also have this weird popping feeling when I pee but maybe it's the baby moving? No liquid or leaking.. I'm so confused. It's been about 4, going on 5 hours feeling like this.. can anyone give me advice? I've been rolling around bed trying to get comfortable but it's not possible. Problem is our doctor isn't answering and we are 2 hours from a hospital.
