What should I do?

Jasmine • February 3rd, 2016.. Was the most amazing day of my life 💙🍼👶🏽
Ok so on Friday, I believe I lost my mucus plug in pieces though.. Since then, my back and hips have been KILLING ME and I've been having constant Braxton hicks.. Also I've had really bad cramping followed by loose stools.. And my baby hasn't been as active as normal.. It's now Monday & still going on... Should I call doctor? I'll be 37 weeks tomorrow ..
