think it has been made in the end of 90's. It was about this couple trying to have a baby. Their friends meet in their house and the movie is about solving the relationships between them. I know this is not very much info... But i remember this part when the woman is laying in bed legs lifted on the wall after sex cause they are told that is the way to get pregnant. And then the doorbell rings and friends have arrived for dinner. And in the end they finally get pregnant. Yay.
