Both my sons bit me at about this age. I was able to train them not to in about a week. Here are the do's and don'ts:
Don't say 'ow' and pull away. (This one's hard). You might scare her and cause a nursing strike, OR (as in my son's case the first time) it might become fun to "see what I can make Mommy do." Shudder.
When she bites, pull her close until she lets go. (Pulling her close will plug her nose and she'll have to let go to breathe.) Takes a few seconds at most.
Then, bring her up to your face, say firmly but gently "no bite" and put her down on the floor. You don't need to leave her there long. 10 seconds at the most.
She'll hate it and start to fuss or cry, and you can pick her up immediately. Do this EVERY time.
(You might add "that hurts mommy" sometimes for later, when she does other things that hurt (and she will) so that she'll know you pull away when she hurts you.)
She will hate being on the floor. And when she learns cause and effect, she'll stop. It really won't take that long.
Here's another thing -- don't try to latch her if she's not hungry. She may bite just because she doesn't want to eat, is bored, and because her teeth hurt. If she bites you 2 times in a row, give it a rest and give her a teether instead.
Believe me, I felt your pain. But it doesn't take long to train her to stop. Good luck!!
