BH or Labor?!?!

I am 33 weeks with my first baby and I have been having Braxton Hicks contractions for the past 4 weeks or so, pretty mild cramps, only last 30 seconds to a minute. She is soooo active. Yesterday I had a lot of cramping and today my whole stomach is cramping and it won’t stop. It’s been cramping for like 5 hours now. It’s not getting more painful or anything, just crazy uncomfortable and yucky feeling. I don’t even feel like eating! Could this be a sign of preterm labor? Or is this normal?
