Do you feel guilty calling out sick?

Usually I push through and teach while sick but I have a horrible cough right now. I can’t say more than a few sentences without a coughing fit. I teach dance and tumbling. Majority of my classes are tumbling and I really don’t want a coughing fit while spotting. Parents are also in the room for every class and I know they won’t want to see me constantly coughing while teaching.
Worst part- thanks to child birth and a weak pelvic floor, a bad coughing fit makes me pee a little and occasionally the pad doesn’t catch what leaks out and I have to change clothes.

Should I feel guilty for calling out today and tomorrow
