Ugh been having lots of tightening in my belly and I feel like im going to be sick and that I gotta poop but I can't. I just wanna puke and go back to bed but I can't. I'm definitely hoping im not in labor here. I just wanna cry! Hopefully we can at least make it to 36weeks which will be Friday. I'm also just hoping it's because of her moving around alot and not labor!
