Too early to start buying Maternity clothes?

Cheyenne

When I began this pregnancy I was already overweight. My weight on the scale has remained stable due to moderate exercise but I only have a few choice outfits that fit me now and I'm tired of wearing the same stuff! I'm almost 12wks.

I haven't gone a shopping yet bc I don't know if it's better to just buy clothes a few sizes up for just go the Maternity route? Have any of you ladies began buying or wearing maternity clothes yet?
