Constantly losing mucus plug?

At 37w5d I lost my first giant chunk of my plug it had a tiny amount of old brown blood and some bright red spots... Two days later on 38w I lost another piece that was also fairly large no blood and again yesterday and today at 38w2d... So does this mean labor is nearing? I was checked yesterday and was only 1 CM.. Ive been starting to walk and ball bounce alot. I am just wanting this baby out. Doctor said I'm ok to start trying to induce labor. Hubby and I have been having sex but not consistent enough i feel.. Its also very uncomfortable for me..
