is my supply done?

Rachel
So my husband is basically useless and I might as well call myself a single parent. My 13 day old newborn is very fussy and needs to be held almost all of the time, making it impossible to pump more than once or twice a day. Just now, after half an hour, I only got a few drops. Is it too late to try to boost my supply? Also, baby won't feed on my breast so I have to pump.
