I have been exclusively breastfeeding my 7 week old son and I've been noticing a decrease in my milk supply over the last week. I went for my 6 week check-up last week and he put me back on birth control (Generess FE) which he said was fine for breastfeeding moms. I was able to pump 10 ounces in between feedings up until this week, now i can only pump an ounce. Please help! I start back to work next week and I really don't want to start him on formula.
