Rude comments people say.

So I'm 17 weeks today and really showing. Definitely have a big bump. Only have one baby in there though. And this is our first baby. Doctor says I look normal and baby is normal size so far. And no maternity clothes yet! This weekend I was in a wedding and two people said to me, 'are there two babies in there?!' Obviously people don't mean it in a rude way but it still hurts. Any ways to cope? Anyone in the same boat?
