Re: Need advice on discipline!!
If you give in to the whining at night, you will reinforce the behavior. It is very hard, I know! I have 3 kids that all required a painful transition into their own rooms, because I was so desperate for sleep, that I allowed them in the bed. The difference is that with a V, once in your bed, you can expect they will always want to be in the bed; in addition, if you do not allow her on your furniture in other rooms (including your roomates), it will be expecting a lot from her to know the difference. Unfairly so at a young age. Ear plugs are a good suggestion, and I hope your roomate does not yell at her to be quiet. It will make it worse.
IMO, I would avoid swats on the butt. A firm no is fine & taking her out to the same potty spot will do. I would also rule out a UTI. If your puppy is going a lot in between potty breaks (so long as you are taking her out frequently) & seems to go without warning like she is surprised too, then rule out health issues. Puppies need very frequent potty breaks, but it is important to make sure she is healthy with so little improvement. UTIs are common in female pups. Our Pumpkin had one @ 8.5 wks, and it was a full month before we got rid of it. That was partly due to her very young age, and the vet did not want to prescribe a strong antibiotic until she was 10+ wks. I would still give her a firm "no," if she had an accident, but they were infrequent once on the meds, because I was taking her out every 15m. It was a lot of potty trips, but I wanted to set her up for success. Once the UTI was resolved, we had zero issues potty training. Another sign of a UTI is frequent squatting when you take her out. Squat & pee with another squat & pee and then another. Frequent licking of the vulva can also signal an infection.
