Extreme pain low in uterus & in lower back 35w4d

Ly

I feel like I’m on my period but 10000x worse. It hurts so bad I can hardly walk and I’m crying. I had a ton of contractions 2 days ago and then randomly the next day and today as well (haven’t timed any) but I’m dilated to a 1 as of yesterday. Should I call the hospital? It hurts so bad
