Cramps that wont go away.

So I'm having pretty bad cramps. I've had them since last night around 9. They seam to be getting stronger each hour. I dont think there Braxton Hicks or regular contractions because I don't have any tightening in my belly just cramps and they stay. they dont give up they just get stronger and more painful if that makes sense. On a 1-10 scale there like a 7. Is this normal for 31w4d
