Loss of mucus plug after sweep

I was due on September 30th... I had a membrane sweep on Monday (40w5d). And I have had very light spotting with very mild cramps since... Similar to mild period cramps... This morning ~2am I think I started losing my mucus plug... Almost 4 days later... Do you think I'm finally in the early stages of labor? Today's makes me 41w1d... Ugh I hope so!!
