Pumping on day 5?

Ashley
My LO is only 5 days old. I've been feeding her on one breast per feeding. She feeds for about 10-20 mins. She's a very sleepy feeder so I never know how long I can keep her awake. Tonight I fed her on the left side for 13 mins and when I was done I noticed my right side had leaked all over my shirt. So I tried to pump the right for a little while and only a drop would come out. Is this normal? Should I just wear breast pads or am I making enough to save?
