Normal or early labor?

I’m 39+1 with my fourth and got checked today. I’m 2cm. I’ve been having some early labor contractions (tightening plus period like cramps) but it hasn’t been anywhere close to active labor contractions. However, I have been feeling pretty nauseous the last couple hours. I’m not having consistent contractions so I don’t think I’m in labor but could the nausea indicate it’s coming? Also, having a bit of diarrhea 🤷🏼‍♀️🤔

Girls. This is my fourth, you’d think I’d know by now but 🤪🤪🤪🤪🤪😅
