I had one of those experiences today. I've read about them on other blogs, but this was the sharpest one I've had. There are not that many women in my company at my level, so we take the opportunity to spend time together as a group at these conferences. Today there were 3 pregnant women and one baby present. When we were introducing ourselves to each other, one of the pregnant women said cheerily, "yes I was married in May, expecting in June - isn't that great!!"
We were married in May.
