Bridesmaid Dress Opinions! HELP!

Brittney
So I'm due Feb 21st and I am a bridesmaid in my BFFs wedding March 11th...when should I go get fitted for the dress!? I'm 6 months now but my belly is a lot smaller than I thought it'd be this point. The dress takes 8 weeks to get in so I can't wait until after baby comes. Thoughts!? Pic of dress is attached.
