Maternity clothes early on

I never thought I would need to wear maternity clothes in the first trimester especially since I've always been quit slim I'm 172 cm tall and was 53 kilos before pregnancy. I bought a few maternity pants for later on when my bump grows but have been wearing them since week 9 or 10 when the bloating started. I just can't stand buttons and zippers anymore!!

Anyone else wearing maternity clothes this early or is it just me?
