Transitioning Back to Breast From Bottle

My daughter is 8 months and so far we have had an easy breastfeeding journey. She got sick last week and was too congested to nurse so I began pumping and bottle feeding to get her through. She is on the mend but still will not nurse. Also, I've never pumped much and am not responding well to it. I maybe get 14 ounces per day? My breasts don't feel empty after a session but nothing else comes out. I'm afraid I am starting to lose my supply. Any tips on how to get her back on he breast? And also any way I can start getting more out of pumping?
