Baby eating too much?

My 3 week old has been fussing on the breast for the past 2 days so today I gave her a bottle of breast milk. It was about 180ml (6oz) and she drank the whole thing.. then she was still crying and I ended up offering the breast where she ate for a further 15min until she fell asleep... does that seem like way too much for one feeding?
