My face is a total breakout...what to use?

Christina

So I never really had acne. I get the occasional pimples, but now its alot worse. I even have a patch that looks like a rash. I think I have combination skin. I get oily at my nose and chin. normally I use whatever face wash I want at Wal-Mart. Lately those face washes aren't helping and some are drying out my skin too much. How do you know what cleanser to use. I'm 13 weeks and 1 day btw.
