Since about half of menstrual fluid is blood, yeah, nightblood women are likely to have black menstrual fluid.

Pregnant nightblood woman: likely, how else would the genetic trait be passed down? (Though my theory is that most Grounders are carriers for the trait, and hence why it pops up randomly in some births.) Similar with nightblood men, nothing has been mentioned to make us believe they're all infertile.
