bloody show? mucus plug??

38 weeks 3 days today, my husband and I attacked one another (sexually,it was glorious!) well I went to get up to find something for us to clean up with (I wear glasses all day everyday) well I looked at him and I think I saw red on his leg (he didn't even look) and he went to clean off and it was gone, inspection of the cloth nothing was there (black fabric) I run to the bathroom and there was like a TINY clot in the toilet and a little shmear of red on the toilet paper. had drs today and I had the dr check and I haven't dilated even though my tum had been contracting since we got there. I went to stand up and leave and my husband pointed out a wet spot on my dress. idk what the hell is going on. I lost my mucus plug with our oldest when they got me in the delivery room, all at once. the spot I *hardly* saw on his hip wasn't big either. drs. next Monday, possibly scheduling an induction. if I am leaking fluid and not just sweating, what would be some warning signs to go in besides labor contractions or heavy bleeding? any advice is appreciated. I mostly just feel like I'm being crazy and paranoid.
