My betta fish is still recovering from a bacterial infection, bur now he's started to make his bubble nest. I know that this is normal, but day by day, his bubbles increase to cover the surface of the water. The rare of bubbles seems a little erratic, some daysbit reduces, and then others increases spontaneously. Should I be concerned that there is something else going on with him? His water is clear and his responses are normal. He is eating properly.

This is normal behavior and no cause for concern. A Bettas bubble nest is unique to each fish in size and pattern. The fact that he is building one is a testament to his recovery and improved health. A sick Betta will not build a bubble nest.
