Sudden breakouts and oily skin. Painful, deep, red zits.?

For about 2 weeks now I have noticed my skin breaking out much more than normal. I am gettins that are VERY red and somewhat painful. I take Yasmin for my acne and it was much better and now it's very bad. What are some reasons I am getting this? I have also noticed I have a lot more oil on my skin but I wash the same as always. What are some ways to stop this? Feel free to IM me for more information.
