Contractions, almost 37 wks

Alyssa
So I cooked breakfast this morning, was contracting a lot, but that happens to me sometimes so I sat down to try to eat and continued to contract. I can't tell how far apart they are or if they are even consistent but they are getting painful. It's probably been close to an hour since this started. I'll be 37 weeks tomorrow and this is my 2nd baby. Can anyone help, is this just Braxton hicks?
