I've had quite a few.
When i announced to everyone at work that i was pregnant, on girl commented "omg are you keeping it?"... not sure why anyone would think i wasn't - i'm 25, have a great job, and my partner and i couldn't be more excited. I sarcastically said back "no, i'm just telling everyone even though i'm not keeping it".
A few weeks later, we had a morning tea after a work meeting and a few of the other girls were fussing about the baby and my growing belly. Then the same girl came up and said "I don't want to alarm you, but my friend was pregnant and the baby was fine all through the pregnancy and then it was still-born... oh i don't want to scare you, i just don't want you to get your hopes up". ???? The thing is, she wasn't even trying to be mean, it's just a really bizarre thing to say. I think she was maybe jealous of the attention i was getting.
My mother also asked me if i'll be getting an "unmarried mothers pension". She has no problem that we aren't married - we told her a long time ago that we don't believe in it for ourselves (we're not religious and have no cultural needs for marriage). I *wish* i could get money for just not being married!
A lot of people have also asked me if i'm have twins. I'm measuring up as 29 weeks - which is spot on. I think i just look bigger because i have a tiny frame. People have commented i look like i've just stuck a basketball under my shirt.
