I woke up this morning with cramps and the worst backache ever, like I need to be in a certain position otherwise it's hard for me to breathe through, it hurts so bad it's making me nauseous. I also felt totally weird in my own skin, I don't really know how to explain it, I tried switching positions thinking maybe I'm just uncomfortable but that didn't help. I don't know how to explain it but it's just weird. Has anyone else felt like that?
