lets talk poop lol

Ke
My soon to be four month old baby girl is exclusively breast fed and she was pooping once a week since 3-4 weeks old. She has started to poop twice a week past two weeks.. sounded normal. Now she is poopin everyday this week.. and all of a sudden started to spit up.. a little not a lot but never has before. 
So when did you ur little once who exclusively breast feeds start to poop everyday.. just wondering if I should be worried or it's normal. 
Btw she has been grunting a lot all day long so I know she trying to work something out.. lol lots of gas too
