what to do?

Samantha • 💍💕👨‍👩‍👧‍👦
My daughter is almost 4 months. 
Hasn't rolled over, not rushing it but I know it should have happened or happen soon. She will go to her side then stop. Also since day one she has hated tummy time. It will last all of 5 min then she starts getting mad. With this being said I'm curious if it is necessary to keep trying. She has great head control an is very strong. Also when being held she pushes off me so I figure it's the same concept. 
Any help or advise ?
