I need some help! (Some tmi)

So I’m a FTM I’m worried what if I’m one of the ones who don’t know they could be in labor.. i know this doesn’t mean i am but this is what has been happening the past few days/ week.. lately I’ve been feeling super nauseous, I throw up sometimes, I’ve been having strong mensural like cramps that make my poop soft and I’ve been passing gas all day.. I’ve been sleeping a lot and have been super foggy where I live a day but it feels like I didn’t.. my Lower back has been hurting more and lighting crotch is terrible I even get it laying down.. and my hips are feeling like nerves are pinched where I can’t readjust to release the pinch like feeling.. I’ve been just feeling so out of it. I’ll be 38 weeks tomorrow appointment Thursday and I hope I made progress bc I want this baby out!!
