Contractions and Diarrhea

CF

I'm 36 weeks and a few days.

I've had diarrhea for three days now. Today started contractions, I guess they would be names "braxton hicks". I didn't experience those with my first pregnancy or I just didn't notice them.

Does this seem pretty normal for the end of pregnancy? Is labor nearing? I had my first 2 days early before his due date. I'm scheduled to have a c-section on the 26th.
