Braxton Hicks?

Hello, so I’m just curious to know if this is some thing to be concerned or not. But so far today, I’ve been getting really bad tightness in my stomach and almost like period cramps. It’s happened on and off since I woke up. They are very brief but some of them were painful and hard to walk through. Some not so bad. With my first I didn’t have Braxton Hicks because what I thought was Braxton Hicks was actual contractions and I had her early due to pre-eclampsia. Just wanted to see what you guys have experienced before I call the dr.
