5month old not rolling over!

Hi everyone, I’m getting nervous. My little girl has only rolled over 3 times and that was about a month ago, and she hasn’t done it again. She also hates belly time. She will push up on her hands and lift her head up but that’s about it on belly time. She turned 5 months old on the 4th. Now I feel like she’s behind and i was looking forward to her sitting up around 6 months but don’t know if that will happen. When she’s laying down on her back she will pull up like she’s doing a crunch and sit up alone for only a few seconds. She does love stand up tho, loves stretching her legs. But anyone else on the same boat. Urgh
