28 weeks pregnant and having menstrual type cramps.

Justine • I`m 20, my boyfriend & I are having baby #1 baby dust to all! :)
I'm 28 weeks pregnant with my first baby, been having menstrual type cramps. And on top of that I had really bad braxon hicks the other days lasted more than an hour.. Should I call the hospital or go to the hospital or just wait it out? Has anyone else had this before?
