Biting is natural for a puppy. Your yelping doesn't help; it makes the problem worse. In a normal dog "family" the mother would let the puppies bite her and yelp in pretend pain (she'll also pretend to be defeated and roll over at times). This is meant to give the puppy confidence and build their doggie abilities.
Remember that if your puppy thinks that biting people is no big deal, they will continue this behavior, and what is bearable at this age can become a serious injury later. If you never train biting out of them, they never learn that this is not an acceptable way to interact with humans. The worst case scenario is that the dog has to be put down one day; so this isn't just about convenience. In the seriousness of it, this isn't fundamentally different from doing whatever it takes to make sure your toddler knows that they cannot play with the stove.
You're overcoming nature, so you have to make sure that every incident of biting is a negative for the puppy. You want to speak the dog's language. Mimic mother dog behavior. If a pup does something that mummy dog needs to correct, she'll grab pup by the neck in a little nip and make a noise. This isn't a nip that hurts; it's a nip that gets attention. Dogs are physical and they respond to physicality.
You can mimic mum dog's behavior by quickly grabbing the pup at the neck and releasing fast, with your fingers stiff like mummy dog's jaw would be. Your fingers are the teeth, essentially. Mum dog will "bite" but she's really pulling her punches and it doesn't hurt. Just like mum dog, you're using your fingers to get puppy's attention with a strong grab that can't be ignored, but which doesn't hurt. You're not restraining, either. You let go immediately. Accompany this motion with a sound--it can be no!, stop!, Ah!, tsk! or anything else you like. Just make sure it's the same every time for everyone in the family. End play and walk away.
These three things will quickly teach the puppy that biting people is not an acceptable (or fun!) way to interact with them. At the same time, teach her other fun ways to be with your family, such as walks, toys, fetch, running, or anything else she enjoys.
