When did you start wearing maternity clothes with your second?

I'm only 6 weeks pregnant but I'm so bloated that I've been unbuttoning my pants while driving bc it's so uncomfortable. I feel ridiculous getting out my maternity pants already..will the bloat go down before the bump comes or should I just wear the momma pants now?
