Egg quality and CM

Serena • Soon to be first time mom. Trying for our little "Caramel Macchiato" Harris. TTC#1
What can I do to have a healthier egg and improve it's quality? How can I get better cm when ovulation comes? As of now I've been drinking TONS of water, eating healthier, and walking for a hour each day and jog/walk when I can. Lost a bit of weight so any tips?
