Having signs..

I'm 37 weeks+2days, i've been losing my mucus plug since Thursday. I lost two big chunks in the early hours of the morning today. I've had mild backaches and cramps nothing severe. I feel sick, swelling on my feet, constantly going for a wee, I have the shivers, urging for stools for the last few days. Are these signs? When will my boy be here? Can't wait now!
