32 weeks with pain/pressure

Amberlynn
I have a question. For the last week or so I have been having some pretty strong Braxton hicks (or at least that's what I think they are...). Since this morning I've been having some really bad period like cramps that I can feel in my back as well. Does anyone know what this could be? My cervix was short at my last appointment, and I am only 32 weeks. Is this normal?
