What size would you get? I am about to have a baby so right now I am 155 lbs but my pre pregnancy weight was 135 and i'm about 5'1. Thanks!

do you have to put on over your head or does it open all the way in the front?

Is the belt attached?

I'm only 5'1, so would this still be short on me? I'm hoping not.
