I work 9-10 hrs a day and normally pump 4 times at work. I normally get between 10-12 oz a day, but today I have pumped 3 times already and have only gotten 5 1/2 oz. I have started my period last night (1st one since birth). My son is 3 months old. Is this normal?? What should I do to pick up my supply again??? I know that me stressing out does not help with the supply issue. I just called my doctor and they are sending me a medical grade pump for me to keep for 6 months. Hopefully that will help in general.
