2 month tummy time help!

My daughter is 10 weeks and still hates tummy time. Everytime I put her on her belly she screams and refuses to budge. She just lays there with her head shoved in the floor. She had her 2 month visit and her pediatrician said that she's a little behind with head support. I've tried everything idk what else to do. Someone help me with some tricks to help baby gain control of her head!
