milk supply & first period

Paige

this past week i had my first period at 2 months pp. it was light and only lasted about 3 and a half days. i started the mini pill on Monday.

ever since i got my period my supply in my left breast is extremely low. when i try to get my baby to eat from it he just moved his head around, pops off and crys. i used to be able to pump at least 2-3 oz from it but now its just a few drops.

my right breast always had a larger supply but its still less than it used to be. he'll eat from it just fine and i can still pump a few oz.

he's also waking up every 2hrs at night and i think its because hes not getting enough to eat.

what do i do? should i just switch to formula? i don't want to be super lopsided
