Braxton Hicks or the real deal?

I've been up since 3 am with this cramping in my lower abdomen. Hurts pretty bad. They last about a minute or so. Just now started keeping track of them for the last hour or so. They are pretty sporadic. 9:13, 9:32, 9:39, 9:49, 9:56, 10:06, 10:15, 10:22. I'm 37 weeks, my c section is scheduled for Nov 2nd. I also had a lot of mucous like discharge about 2 hours ago. I know nobody here is a doctor, but what do you ladies think?
