Mucus but not the plug?

I didn't see my plug at all till I had my membranes stripped a 2nd time at 42 weeks with #1. I am experiencing all kinds of "feelings" with #2 that I didn't with #1, like low, painless contractions, etc...Last night I wiped and a huge glob of gross yellow mucus came out, only once. It was definitely not the plug, though. Is this at least a sign of..something? I have no idea, since this is essentially the first time my body might be doing "labor". you know? Thanks!
