Its just one of those thing Ryn. You will have one person tell you that your tiny (like I did last week) then someone tell you in the next minute that you look ready to pop.
So many people like to have an opinion on where our pregnancies are at, and really - alot of it is just conversation starting!
I have been one of those people that is a late bloomer too - but no fear, people know I'm pregnant now. Even yet I dont get the respect someone in my condition should get - you know, being offered a seat or a hand cause I just dont look as far along as I am.

Try not to let people get to you, its better for you to be smaller - less stretchies, less weight to lose, and you are far more comfortable!! And as for maternity clothes - who really wants to wear them anyway Save your money and wear normal clothes as long as you can!
