Milk Supply & Birth Control

Brianna
Okay so I'm 2 months postpartum and I've been giving my lo expressed milk since she was about a week old and I usually was always a over producer by about half an once to two ounces but recently it seems like I've been producing less and less. I've recently got on nuvaring it's been three weeks so far and idk whether there's less milk because of the bc or I was sick recently. Anyone tried breastfeeding with nuvaring that wanna share their experiences?
