Contractions?

Whitney
So since yesterday my stomach has been feeling kinda weird I'm not sure if I'm having contractions or just Braxton hicks...but yesterday my stomach was super tight and very uncomfortable and no matter what I did it didn't make it better...I had a few cramps with it but I took a bath and just went I sleep last night my stomach cramped a little and now as I'm sittin here my stomach is just feeling crampy and my back..it's kinda coming and going but can't really tell...I just don't know what to do or what's going on...needing advice..
