My 10 week old golden won't stop biting - is this normal??

We just brought home our golden retriever puppy Maple three days ago and she is SO bitey. Like constantly. My hands are covered in little scratches and she especially goes for my ankles when i'm walking. I know puppies bite but this feels like a lot?

She's super playful otherwise and clearly not aggressive, it's more like she just doesn't know what else to do with her mouth. We've been saying "no" firmly but she just gets more excited. Is this normal for goldens specifically or did we just get an extra spicy one lol

Any tips from people who've been through this would be really appreciated. first time golden owner and i don't want to mess up her training right at the start.
