3 weeks post op Full Tummy Tuck, I have a slight hard bulge above belly button. Is this normal?

I am exactly 3 weeks post full tummy tuck with muscle repair. One week postop, I picked up my laptop to walk to my car(regretting). Also I had coughs that same day. Now there is a small bulge and hard feeling above my belly button. Did I damage my muscle repair and strain my sutures? I have attached some pictures. I cant capture the bulge in pictures well. Also I am wondering once swelling goes down, will the skin above my belly button hang and not have a washboard abs appearance? Thanks.
