There are many folks who let their dogs sleep in their bed with them. Many have found their puppy seems to sleep better or longer when they are in the same bed. I think it is a very hard habit to break, so if you do not think you will want the puppy sleeping in bed with you 6 months from now or a year from now, I would not let her do it now. Plus, if she does have an accident, she's in your bed so it would be harder to clean up. If you are happy with the arrangement, you do not have to change.
Also, puppy's bones are still growing and more easily damaged when jumping from heights. I would not let the puppy jump off the bed if your bed is up on a frame and the surface is more than about one foot off the ground. Jumping down puts a lot of impact stress on their elbows and shoulders and can be harmful to growing bones.
I hope you and your puppy are doing well!
