ugh rolling over

Is anyone else's 5 month old still not rolling over?? Ryker has rolled over 4 times tummy to back like 2 weeks ago but now won't. He still hates tummy time. Lays there and screams with his face in the floor after like 1 minute. I feel like its my fault BC being a full time working mom, when I come home all I want to do is hold and cuddle with him. Is it BC I haven't given him enough tummy time or is this still a milestone that's to be reached in the next month? I just tend to stress myself out but worried I did harm by constant cuddling and holding him.
