I EBF and started the pill 8 days ago; I've noticed a definite decrease in my supply. My breasts take longer to feel full, and 'feel' empty for hours after feeding. I've never had this before. I don't get as much when I pump either, about an ounce short on each side. I looked up on Kellymom and it said the mini pill could affect supply in some women. 
For those taking the MP, have you noticed a decrease in supply? 
Does it eventually get back to where it was pre-pill? 
TIA

Re: Mini Pill affecting supply?
This site says your boobs will normalize and not feel full, and feel almost like pre-pregnancy boobs. Often women think it's a drop in supply and give up BFing, when in reality that's just what our boobs do. May be what is going on...
