My pregnant sister just lost her mucus plug, she is 37 weeks pregnant. Could this be a sign that the time could be near?

My sister is 37 weeks along. They say it can be anytime now between now and November 13. The mucus plug has now been lost. Im wondering if the time could be sooner than we think?
