Feeling loose down stairs WTF?

im pregnant with #2 after a (7 year) gap and I for the first time in weeks got the chance to have some romance with my partner last night and I noticed that I felt like I was loose He said it was normal but I felt that it was lose its strange ive never had that feeling! Not with #1 and not after #1 and not during this pregnancy until now although I am experiencing some cramps and a lot of discharge which I would even say slowly losing my plug.... 32wkd 3 days

Anyone els felt like this or know what is happening?? Could I be dilating? Which explains the mucus??
