Ok. What the heck is going on?

Hi, I'm 38 weeks and 1 day with my second child. I was induced with my first, so excuse if this sounds dumb or ignorant on my part.

Yesterday I had bloody show for a good amount of time yesterday, about half the day. I had a sweep the morning of the day before. Was expecting it. But, this morning I lost my mucus plug, it was huge! I've had strong but painless (yet uncomfortable) contractions all day, about 15 minutes apart. Every time I wipe, there's more mucus, like a whole plug every time. I just had a bad bout of diarrhea...am I going into labor or wth is going on?
