YAZ causing vaginal irritation

Patient: Hi, I recently started YAZ and it has been a week. Since starting on the pill, I have felt irritation such as itch and soreness in my vaginal area, it has caused so much discomfort that I want to go off the pill. Would you know what is causing this discomfort, and any recommendations for other brands of bc? Is stopping mid-cycle bad for the body, and would you advise against changing a brand mid cycle?

Symptoms: Itch, sore
