Help!

I just started a new pill which I was on few years ago but changed back after the other one was causing me to be really moody and angry. I been with my bf now for 4 and a half years and have great sex life.

However I have recently been getting discharge that is white and smells a little. I pee before and after sex and clean my vaginal area daily. The only thing changed is my pill from rigevidon to microgynon. Has anyone had discharge from changing the pill?
