I'm the last person to be offering potty training advice!
But I would put down more puppy pads, so that if she gets a little ways from her bed she can't help but hit a puppy pad. And when you put a new one down, soak up a little urine so she recognizes it as a potty spot. I know they're supposed to have a smell that tells them it's where to go, but not sure how good that is.
