36 weeks, Braxton Hicks or contractions?

Patricia

On Saturday I started noticing some of my mucus plug coming out, clear and like jelly, everyday I have been having bits come away. the past 2days I have had a lot of loose stools and today everytime I eat I have had almost instant dihorea. for the last 2 hours I have been having cramps in my bump and lower back every 3-4mins. can this just be Braxton Hicks?
