no it doesn't, but u feel so may be becoz u r not comfortable during that time. drink lots of fluids n take rest to maintain the supply.

No that's a myth.. U can drink lots of fluids n juice..

periods will never lower your breast milk supply

nop. both are not connected. i am still feeding my 17 months old daughter and i am having no issues with supply. periods or no periods. make sure ur water intake is good.

I don't think so. if your protein intake is good along with good liquid intake and calcium intake, I think your best milk supply will be fine.
