This is my first baby I’m 37 + 5 days everyone talks about wart labor what is vs real labor? What should I look out for for real labor I know if you drink water and lay on your left side it doesn’t go away it’s real labor but how do you time your contractions and everything

I’m scared I’m going to either one get sent home from the hospital cuz I’m not in labor or two not make it to the hospital or be in so much pain getting there and won’t be able to get an epidural. I’m so scared of labor
