Are these yawns affecting the shape of my nose? Or just cautious about the stitches potentially being pulled?

On my post OP Rhinoplasty instructions it said no yawning, even underlined.....although I dont know about you but when I need to yawn there is no stopping it, are these yawns affecting the shape of my nose? Or just cautious about the stitches potentially being pulled? Had a constant yawning spree for whatever reason day 4-5.
