When you do have a big belly you won't care what other people think. You'll be too happy at your own good fortune.

Oh.....and what Cranky Kitten said is so true. It starts when you fall pg and just continues throughout the years. Someone will always be judgemental about something. Don't waste energy worrying about it. Especially when it hasn't happened yet. As a PP said, people may surprise you with how happy and supportive they can be.

All the best!
