Am I in labor or what??

I’ve been losing pieces of my mucus plug in the last 24 hours (no blood, just clear and jelly-like chunks). About 3 hours ago I think my water started to leak. I felt some pressure and then a release and some clear, no-smell liquid filled my pad. Since I was wearing a pad, I really can’t tell how much came out. I don’t feel any contractions, but I have a very slight cramping in only my left side. I was just at L&D yesterday afternoon and they sent me home (I never even saw a doctor or had any tests/exams done, they just said the babies heart rate and my blood pressure were ok).

What do you guys think?
