11 week old puppy limping after falling off bed

My 11 week old basset hound puppy was roughhousing in the bed with our older basset and fell off the bed. It is roughly a 3 ft drop onto carpet. I think she landed on her side, not her head.

Initially she was not putting any weight on her back leg and crying. After about an hour, she is still limping, but manipulating the leg doesn’t seem to hurt her. She is walking around our back yard and interested in sniffing and rolling in the grass. She seems slightly sleepier than normal this morning but not sure if I’m reading into it too much.

I’m debating on taking her to the vet, but not sure how much time to wait or if I need to take her at all. Any advice on if / when I should take her to the vet? Symptoms to watch out for? Ways to ease her limp at home?
