Early labor maybe?

Alexis

I have been having lots of contractions today, even 7 real bad ones in an hour that felt like someone was ripping out the lower part of my spine, went to the hospital and it showed a ton of contractions that are pretty steady but I got sent home because my dilation hasn't moved since Sunday. I am 38+1, could this be a sign of early labor? I have also felt nauseous as well
