This month my period is a very light color.. more of a pinkish color. is this normal. i've been taking hairfinity/vitamin c 4 two weeks now.

Not related: I don't think taking the Hairfinity vitamins has anything to do with your period. The ingredients are vitamin C (as you mention) along with calcium, some B vitamins, hydrolyzed collagen and the herb horsetail! It is normal for there to be less blood intermixed with vaginal secretions some months. I wouldn't worry about this. Good wishes:)
