32 week contractions

Ti

I has my first NST yesterday (32 weeks 4 days). I kept having pressure around my belly button (contractions) every 3-4 minutes. Then after being on the monitor for an hour I had a big contraction and about came off the bed. I said I have to pee. So they let me go pee then asked if I wanted to be monitored more or go home and monitored. I opted to go home.

Has anyone else had contractions this close together while on NST or have big contractions?
