Not wanting to nurse @ 3 months - help

Useonfire

My DD is 3mo and has been fighting me at the breast for a few days now.  She used to refuse to take a bottle, and now it seems to be the other way around.  She was refusing my left boob for a while on and off and now it's both! This is driving me nuts.  She only usually gets one bottle of pumped milk if she wakes up in the middle of the night so it's not even like she's bottle fed half the time What can I do??
