Early labor?..

I am having a few signs/symptoms but I may be overreacting.. I am 34+2 today.. I'm having urinary symptoms (no UTI, had it checked) increased contractions even though they are not regular or very strong, some inconsistent period like cramping, diarrhea, slight nausea, dizziness, and I think I've lost some of my mucus plug. And, found out this week that I am dilated 1cm and 20% thinned out. I'm pretty stressed about it all.. Am I being way over sensitive?? Or are these signs that I may be on the road to labor?
