Is it okay to switch bith control pills mid-pack?

All birth control pills make me seriously break out in spots, i've been on 10 different types in 2 years. I've got scars from them, before going on the pill i had perfect skin. I've been on Diannete for the last year and occasionally i switch to Yasmin (an acne treatment!) because i know the Diannete is high dose and there's higher risks ociated with it. I switched back to Yasmin a couple of weeks ago, I've all ready got 4 spots (none on Diannet)!! This is crazy, plus i've just started dating a really nice guy :( I'm 20, shouldn't be having this problem. I want to switch back to Diannete. Can i just start taking it again and stop taking yasmin?
