Early Labor ...please explain it to me , I think I might be in it. .

depends, are you getting any contractions?

I've had pressure in my ass since 2:30 still going now my lower back is starting to hurt but she's moving but my stomach is also getting tight.

if you’re feeling unsure if you may be in labor you can always call a 24/7 nurse and they’ll tell you whether to go in or not. It could be back labor but i never had that so i’m not sure 😭

Well my OBGYN dosent have a 24 hour nurse sadly. And I have an ob appointment tommrow I just scared

If your uterus is consistently contracting, time the contractions.

Early labor? You are 38 weeks your right on schedule :) good luck
