Hello Birdiefu! (not birdie flu, I hope..boom tish!)
If you make all your short rows in one block, your radius of curvature will be smaller than if you spread out the short rows in between normal, straight-across rows.
That's a nice top! but, I think short-rows would emphasise your belly too much! Maybe you should flare out the lower half of the top instead, like a "baby-doll" style dress. And it will drape gently over your newly developing child - and you can still wear it after baby is born. Good luck - with both knitting & gestating!
