No more milk with breastfeeding!?

Florence
My little girl is now 5 months old. I've been mostly breastfeeding her and supplementing at most once a day. I'd take formula if I go out. The most I've been able to pump at one point was 6 ounces. Then it went down to 2 ounces, but the baby had plenty to eat at the breast, so I wasn't too worried. Just recently, I went on vacation to my in-laws's house. That disrupted my BFing. Now, I'm home and I get DROPS at the pump. I've tried supplements, relaxing, lots of water...nothing. So frustrated!!!
