You are not alone I posted this on another thread a few days ok 
If your puppy bites you, you need to ignore the behaviour and remove “yourself” from the interaction without any drama, no need to say anything or do anything.
This means to your puppy the fun is over, the play has ended and more importantly the attention is over.
If you behaviour is to hard for you to ignore then go behind a door or baby gate where your puppy does not have access to continue nipping at you.
If your puppy tries to nip at you when you return, remove yourself again- It may seem a really repetitive process but a really important lesson to learn. When your puppy offer appropriate interaction (no nipping) you stay. Any nipping and you go away..
You should begin to see a major decrease in the intensity of biting as well as the amount of biting attempts within a few days.
Other things to think about
It is really important to have a management place for your puppy, such as a play pen. It gives you a break from your puppy and is a clam place for your puppy to settle down if he gets to excited.
Consider your puppies preference for permissible items to chew! (non-human items – so no slippers or shoes, this will end in disaster!) Think about the texture, some puppies like soft latex toys to mouth, other like plush toys or rubbery toys (often a hard chew toy is not the same!) Consider items for your puppy to chew or lick- such as Kong toys or lick mats to help keep them entertained.
Things that we may think are punishing, like pushing your puppy away, yelling at him etc, can be considered fun behaviours for your puppy and can encourage biting.
It is no wonder than yelping as the puppy bites you as you have an over aroused puppy and then you squeal at it - this just winds up the puppy even more.
An over aroused puppy is a bitey puppy! Puppies need a lot of sleep so look to increase this if possible.
