Think I'm in labor 😳

Had a membrane sweep today at 2:00pm. She said it wouldn't put me in labor today but I'm second guessing her lol. I'm an hour from the hospital and waiting for it to get a little more progressed so they won't send me home. Pretty sure I'm not imagining it though. Feel much different then the little twinges I've been feeling when I move a certain way. Just sitting here my back and lower abdomen are giving me a hard time on and off 😱 I'll be 38 weeks tomorrow. Feeling very nauseous and like I want to sleep but can't get comfortable without feeling like I'm going to puke 🤔
