Don't allow the behaviour. Period. When she bites, or preferably when you see the bite coming, restrain her (as gently as you can) and don't let her go until she quits trying to bite you. I use a "bear hug" to do this, being careful the dog cannot reach my face. If she starts again, rinse, repeat. She is self rewarding in some way with the biting and you need to shut this down as it appears to be turning into a habit. When you release her, if she does not try to bite, lots of praise. If she tries to bite again, a firm "no" and restrain again.
Another option is when she goes for your hand, thrust your fingers down her throat so she gags. She may then redirect to another part of your body, so get your hand in the way and repeat.
This pup has not been socialized. Her mother and siblings should have taught her that constant biting is not acceptable, and since apparently that didn't happen, it is up to you to show her that biting is off limits.
None of this is pleasant, but now is the time to sort this. Puppy teeth are sharp and it won't be fun for you, and yes, she may grow out of it, but letting it become a habit isn't something you want to happen. She is young, and hopefully if you kindly and consistently stop her from indulging in this behaviour, she will give it up.
You might want to wear a pair of heavy gloves until you get a handle on this. If she is used to walking on a leash, another thought would be to let her drag a leash and use it to pull her away from any biting attempt. Good luck!
