birth control
"I've recently come off yasmin due to reading about the increased risk of blood clots. However I was on it for a number of years and had an OK experience with it. 

The positives were I had no headaches (I had excruciating migraines with marvelon) and my skin was perfect - only the occasional spot before my period similar to what it was like on diannette. 

However the bad side effects for me were weight gain, I put on roughly half a stone which no matter what I couldn't shift and I was tired all the time. I also had zero sex drive.

I'd recommend trying yasmin if you're concerned about acne and particularly if you're looking to come off diannette. However as I say it's not perfect and everyone reacts differently."
