I'm about 10 weeks pregnant and my fiance, now husband, and I went to the States to visit my family. The instant we told my parents I was pregnant and that we were really pleased and excited about it, they looked at me speculatively and the first thing they said was not "Congratulations!" but "Oh. Then this would be a really good time for you to lose some weight!"
If they'd actually said something nice about the pregnancy first, then I wouldn't mind so much, but they never said "Congratulations!" or anything like it at all.
DH and I were both hurt by this. We thought if anyone could tell us if we were BU it would be here. (He likes to read over my shoulder as he thinks all of you tend to have very sensible attitudes.
