why does my bunny do this 🙁

Hi! A lot of you may have seen my previous posts. Quick question:

Daisy got spayed 8 days ago and now likes to do this to me? She will also nip me unprovoked. Maybe she thinks I’m going to take her back to the vet? I don’t know what I’m doing wrong, she has unlimited hay, she gets food and toys and time to play.

Also the reason she is on this mattress is because she peed on the sheets and while they’re being washed she hopped on it again. Wow, as I type this she peed again. 😐

She still comes up to me for pets but also nibbles like this a lot. Maybe it’s because of her upbringing, how she was neglected by my sister? I don’t know. Just looking for some answers!
