Help! Activated Charcoal and Terconazole

Okay so last night I purchased activated charcoal. I used one capsule and felt the effects immediately. I had to go to the bathroom asap. Today my yeast infection was really bothering me (ive felt like i have had it for months and occasionally i smell a fishy odor) and so my sister lied to her doctor and got me a perscription. I am wondering if I can take it even though it is a vaginal applicator AS Well as the Activated charcoal. Any immediate feedback would be great since its about to be two hours and i will make a decision.

P.s.
i have gone off my diet horribly eating every form of white bread that i could today.
