4 months no rolling!?

My baby is four months old and maybe has rolled a few times I’m so frustrated I have done tummy time with her since day one she’s dosnt mind it she can do it for about 30 minutes without a fuss... she has never rolled from back to belly hasn’t found her toes she will grab her knees though I just saw an ig post that it can be possible because of too much tummy time I’m so overwhelmed all you hear is tummy time tummy time tummy time now an ig pt is saying to much ugh I’m a first time mom
