'No' means absolutely nothing to a puppy. If delivered in a stern voice (I'm not assuming it is, but it's hard to say no in a happy voice) it will just teach her to pee in private where you will find it days or weeks later.
The key is to eliminate opportunities. Your pup is either outside with you, in her crate to tethered to you at all times. Yes, it's a gigantic PIA, but it won't be forever and, if you're consistent, it will be over before you know it.
At ten weeks, she'll need to go outside more often than you would have thought possible, and you'll need to go with her.
If she is peeing (inside and out) a truly excessive amount, you might have your vet check her for a urinary tract infection (UTI.) It's easily treatable but can become serious if untreated.
