Saying "No" means absolutely nothing to her, because puppies don't speak English. She's probably acting that way because she's confused, frustrated or simply thinks you're playing a game (you 'bark' at her - she barks back) Try just keeping a toy constantly at the ready & immediately redirect her to it (keep it in between your hands & her puppy-shark teeth) so she bites that instead of you.
If she persists in ignoring the toy & instead goes for your hands, simply stop playing & walk away from her for a minute or two. She will learn that teeth on skin = fun stops.
If you do some googling, look for 'Kikopet' youtube videos. Emily has some wonderful ones that address this very issue (along with tons of other puppy raising helpful tips on other issues)
