Ok let me tell you what's happening here at work right now... There are about 5 of us all due within 4-5 wks of each other (No there was no over night work do that month!)
I am having my second I am short & started wearing maternity clothes aty 12wks as my gut just would not suck in enough to wear my normal clothes usually a size 10-12. Pretty much people knew & could tell by then too! My OB has weighed me once only & each time says I look great & no need to weigh me! I know I have gained a lot more than my first preg & mostly in my thighs & butt (as well as belly) But everyone says I look great (which I do!) hee hee!

Another lady is taller her second too, only told people she was pregnant in last few weeks as noone could tell, she is a bit taller but also a health nut, I give in to my cravings!!!! hee hee!

Another lady due before me by 3 days & with whom I am close with, is having her first, is very tall & lean & her sister & Mum never wore maternity clothes as they never sported pregnant bellies at all? She is exactly the same, although wears maternity pants just & some maternity tops I was wearing & grew out of, I have given to her & she showed me it on her & it swims on her! She was a size 14 prior to preg, but mostly due to height!
Her OB actually gave her a diet she should fdollow due to the amount of weight she has gained being excessive!
I tore it up for her! As she has 12 wks to go, most people could not tell she was preg let alone 28 wks preg, so how absolutely ridiculous for her ob to give her a diet to follow! I told her to go to mine, especially when he told her off last appointment & made her cry for the next 2 days befoire herself & hubby left for a 2 weeks holiday she was miserable She is making herself sick with worry that her next appointment on Saturday he will weigh her & make her feel like **** again, I shudder to think what he'd think of me! The medecine ball on legs!
I weighed about 50-52kgs when I fell preg with first & was 72kgs the day i gave birth, within 4 wks of being a zombie Mum & not at all dieting or exercising I was 46kgs! Purely from exhaustion I think!
I weighed about 58kgs when I fell preg this time & already weigh more than 70kgs, I really don't care, as my OB says all looks good to me!

So just ignore those comments as they are un true & often do more harm than good!
