I know it's hard, but she would do better with crate or pen training right now. At 8 weeks, she still has limited control over elimination behaviors. It's not fair to her (or you in the long run) not to get her started on the right paw.
What I do with young pups is set up a night time crate in my bedroom so I can hear when s/he needs to go potty. When I got my first toy pup, I got a small crate and set in on a little end table right beside the bed - not as good as snuggling, but I could still see and hear her without getting my lazy self out of bed.
Toy pups 'graduate' to an X-pen with a small open crate and a potty pad until I know they are 1) ready to sleep in my bed without accidents, and 2) able to safely get on/off the bed (via the stairs I have set up for them) to use the potty pad which is eventually moved out of my room.
The other possible danger of sleeping with a puppy that small is the risk of rolling over her and smothering her. I know it doesn't feel like a risk, but a friend of mine is an investigator for child death and injury - you'd be surprised just how many babies are smothered to death by sleeping in their parents' bed. It's heartbreaking. Remember now, a human pup is a great deal larger than a Yorkie pup.
Just a head's up.
