Acne will not go away, what should I do?

I'm currently under a dermatologists plan that I started in mid February. I use Cetaphil as my cleanser (once in the morning, once at night) to clean my face before applying my prescriptions. I use Acanya gel (clindamycin phosphate and benzoyl peroxide) in the morning, and then apply Differin gel (adapalene) in the evening. I also take Doryx (antibiotic) once a day, and my face has cleared up, but then started breaking out more. Right next to my nose underneath my eyes there's a little acne left, but my forehead pretty much refuses to clear even though before I started I didn't even have acne on my forehead at all. My next check up is in July. Should I wait and talk with him, or is there anything I can do immediately to help with my skin?
