Braxton hicks

I was wondering if anyone else has been having these now more often. Yesterday they started maybe 2 or 3 an hour. Fell asleep and woke up around 5am to them every 7-10 mins.i got up twice and kept switching positions.  For an hour and a half. I had about 7 or 8 in one hour along with some cramps but they didn't get stronger. I drank water and layed back down. Since they didn't get stronger I fell asleep.woke up and they aren't constant anymore maybe just like one every hour. Has anyone else experienced that? Should I still call my doctor or is that normal? I drank about 8 cups of water yesterday but idk if I was still dehydrated
