Stopping birth control - Yasmin?

hey. I've been on a course of Yasmin for a year to clear my skin n regulate my period, I take my last pack this month. Well, my skin is clear n my period is like clockwork, but I've had terrible mood swings, frequent urination, weight gain n headaches. I've read some horror stories about coming off the pill on certain forums about how some girls have broken out, put on more weight etc. Any advice on how I can maintain my clear skin, lose weight n keep my period regular when I stop the pill at the end of this month. Please help, thank u :)
