You simply need to acknowledge that it is hard for us. Offer sympathy when it seems to be needed and understand that there are some times when going out where there are going to be pregnant women and babies is sometimes just too much for us. Don't take it personally when that happens.

And most importantly - NEVER try the line "I understand how you feel because it took us 6 months to conceive". Yes, it is difficult any time you are TTC and a cycle is unsuccessful, but there's no way in the world 3 months, 6 months, etc can correspond to a year or more, and add the knowledge that there are issues, which make natural conception utterly impossible for some of us. There's no understanding what it is like unless you have lived through it yourself. I know friends who say things like that are very well-meaning... but there's just no comparison. I look back to the first few months when we were TTC, and it was disappointing to see a cycle fail (and hear of other successes) at the time, but it's nothing like the complete heart-rending agony that I experience now.
