Feeling awful

I've been working out and trying to eat well my whole pregnancy (25w on Sat). I just flew home for my brother's wedding and it's the first time anyone has seen me pregnant - all I keep hearing is how big I am and it's absolutely destroying me. I sill wear a size small at motherhood maternity and can wear my size 4 pants/shorts with a hairband around the button loop.  My boobs are the biggest issue as I am now 5'3" with a 34DDD bra size, but I just think it's so rude for my own family to be so critical.
