fungal infection in toenail

Awhile ago, I started taking fungal defense to get rid of a fungal infection in my toenail and vaginitis. I did the full course of that, and both of my symptoms started to get better. In particular the toenail, it was almost clear again.

Then i started taking primal defense after the fungal defense, and the fungal infection in my toe appears to have gotten a little worse, as less of the toenail is now looking normal. I'm a bit worried because i want my normal toenail back! Is this common? or have i been doing something wrong?

thanks :)
