Feeling fat and frustrated!

Getting rather overwhelmed by the 'aren't you looking big' / 'is there definitely only one' / 'are you sure you're not further along' comments. It's hard not to be rude in response but I do end up feeling quite upset by it. Here's me at 24 weeks. Obviously pretty huge. I'm not sure why as baby was measuring small at the last scan and I've not actually put all that much weight on. I'm hoping the growth will ease up for a bit now.
