Yup. Just be comfortable! Pregnancy is too long to stay uncomfy. I don't buy maternity clothes, but I had to buy bigger shirts than normal at 5 weeks along (I had just lost a bunch of weight before getting pregnant and got rid of all my big clothes). Those shirts are already too small, so I guess I need to go shopping again! Thank goodness I'm having another winter baby so I can hide behind a coat throughout third trimester instead of buying even bigger clothes. Haha
