Wow - I never thought of it but that sounds like a really smart connection.....it's a fact that estrogen depresses milk supply: You're probably right about the fluctuating hormones around AF having alot to do with it. Mebbe that's why BF mom's don't usually get AF? ....designed that way so it doesn't interfere with supply.......
Something to wonder about. If you're right the problem should resolve itself fairly soon for you

.....but mebbe come back again next mth
I'd be curious, let us know!
