Feeing weird 36w4d

Well from last night and all today I just feel really off. The baby is moving like normal, but my whole body just aches. I keep having cramps lightning crotch and pressure in my bum, I have a sharp pain on my left side but it’s not from baby sticking out, but hurts when I move or if I touch that area. When I’m up and moving I can’t do it for long because I get kinda dizzy and light headed, and I ate today but constantly feel nauseous. I drank like 4 bottles of water and an Arizona tea, and still drinking more water. It was a night mare trying to sleep last night because I just hurt so much especially my back and hips and shoulders, then when I lay on my back it’s like I can’t freaking breathe... 😩 any other mommas feeling like this? Is this just normal? Any cause for concern? I’m a FTM and don’t really know what to expect, so thank you for any advice!
