Labor contractions?

Carloline

I’m 36 weeks pregnant and starting around 11:45 last night I could tell I was starting to have some contractions. They weren’t like my usual Braxton Hicks where my stomach just tightens up. My stomach was tightening and then also having period like cramps. That went on until about 4:00am and then I was finally able to fall asleep. I took a bath in the middle of the night, drank lots of water, changed positions and nothing helped. When I woke up this morning they started up again and it’s now 4:00pm and they’ve been coming every 2-6 minutes or so lasting about a minute, sometimes more. Every so often they’ll stop for 30-60 minutes. Should I go in? Or would this still be considered Braxton Hicks?
