Breast milk Oversupply?

Peach

What is considered an oversupply of breast milk? I have a 5 day old and seem to be making way more milk than she needs. My breasts get VERY engorged and leak A LOT!! Is this normal this early and will it calm down over time? It is very uncomfortable being engorged so much and so often, so I hope it slows down as my body learns her feeding pattern.
