Am I compromising my supply?

Jo
Ok so I'm ebf my 4 month old son I pump about 16 oz at work in an 8 hour period today I only pumped 5 oz because I got so busy at work but my boobies don't feel hard or full its it normal to not feel that way. He is eating cereal now and bananas but still drinks my milk am I compromising my supply? Any input is appreciated thanks!
