This is my third pregnancy. First: 19 3/4 inches, 7#s5oz, 39w4d. Second: 19 3/4 inches, 6#s5oz, 38w0d. I'm due November 28, and currently 36 weeks. About two days ago I lost my m plug. The day before that I swelled up like a balloon. The day after losing it, I've started getting contractions. At least I think I have. Here's my question, am I having contractions or is it just strong bm cramps?
