41w finally losing mucus plug!

Heather
41 weeks today and scheduled to be induced tomorrow at 8 AM, but started losing my mucus plug!  At first it was just a little but a lot just came out!  Anyone know if that's a good sign that labor is close?  I've been having cramps and BH for a few days so hoping our baby will start to come on his own tonight.  Anyone else overdue and/or going to be induced soon?
