Skipped a side feeding

So ladies. In the middle of the night I nursed on my left side and just now when he woke I nursed him on the left again because well it was a busy day and long night and when I woke I didn't remember. Well as soon as my left breast letdown my right started leaking non stop. So I had to pump that side after nursing my little one and I got 5 oz. But is it normal that I really want to cry about what I leaked? I mean I was wearing thick cotton breast pad and it soaked through that my bra and my shirt!! I feel like that was wasted milk.
