Breaking out on yasmin pill after being on it for 15 days is it normal?

I've started taking the yasmin pill after 3 days I saw a huge improvement but 2day on the 15th day I broke out I have small pimples on my face. Is it normal? Will it go away? I also wanna know after taking the pill when will I expect to get my period? 1stly I took the pill wrong. I didn't have my period and so I took the pill. Ps I never had . I'm taking the pill solely for my acne
