For me it depends who and how they ask... I actually had a co-worker ask me a full lunch table of co-workers if we were trying! VERY inappropriate and I let her know that! I've actually started telling people we may not be able to, I just don't tell them why, they usually stop asking after I say that. Between my PCOS and DH's counts, that's not far from the truth. We can't afford the time or money for IVF so if we have to get to that point, there will be no children for us. People usually realize they've hit a nerve when they and also realize that it's not easy for everyone and that maybe they shouldn't get so personal if they don't want to hear the truth
