18wks PP. period! Hair loss!!

Hello! I have been EBF LO for 18wks straight now and today I started my period 😩…just spotting but first blood show. And I’ve noticed that I am loosing tons of hair which I don’t mind cuz I rock the mom bun since LO likes to touch it 🥰 need a cut and really want to go shoulder length for the summer.

Anything else I should be worried about? Lol

I’ve heard that your period slows down milk supply?? Is that false?

Any additional vitamins that I should take now besides prenatals?

TIA ;)
