Contractions or upset stomach

I woke up today and I knew it was going to be a cramps day. Just a day well I had period like cramps throughout the day. Today I have also been feeling the need to poo I've went twice and I never really felt finished because the cramp that pushed me to go to the bathroom was still there. Do I just have an upset stomache or is this just another version of Braxton hicks? I'm 39 +1
