Is this your 1st or 2nd baby?
With my first, I didn't put on any weight or need maternity clothes until about week 27 but with this one, my second, things were getting tight almost immediately despite no weight gain but by 12 weeks I had suddenly put on a stone and needed maternity wear! Fortunately, that weight has stayed the same to date but I definitely feel heavier.
Just wear whatever is comfortable for you and enjoy
