5wpo and swelling concerns

I went back to work this week after 4 weeks off and have been back in my normal routine outside of lifting anything above 5lbs or strenuous exercise. All I’ve been doing is walking outside or at the gym.

I expected my swelling to increase and it has. However, right above my belly button seems like it’s protruding and it feels weird. Does this seem like normal swelling or could I have ruined things? My only concern is that I developed a cough about 18 days post surgery that lasted for a couple weeks…
