A: Here's the answer from my "Embarrassing Questions" article:
Can I get a tattoo if I'm on my period?
A tattoo will not affect your period, and being on your period will not affect your tattoo. The only thing you might want to consider is your pain tolerance - if you're already cramping and uncomfortable, you might not want to add the discomfort of a tattoo to that. But there is no reason you can't get a tattoo when you're on your period.
