Me too with the sexy dreams and it's usually not my dh! probably guilt about not putting out cause in my dreams dh usually knows I'm going off with some other guy!
I'm very paranoid about dtd while pg. I spot easily and it freaks me out so I put it off as long as possible. so far, I've been very lucky this pg and no spot (knock on wood).
Mulva, could she tell you if the placenta was anterior? I'm worried I will get a lame u/s person too. it's like "come on people! give me something to obsess about!!!" Did you get a hr?
