I was told not to have any sexual experiences..lol not even anything that may be slightly nice..I had bleeding at 30 weeks and the first thing my obst said "I told you not to do anything!" I told him we hadnt since the IVF transfer. They are all different, Good luck for Wed, I'm sure it will go fine. As for all the checkups to be honest after 30 weeks I was so relaxed thinking that any change would of had to of been picked up by now and dreaded the hr to the obst office.
