I took Yasmin for about 2 years, and didn't seem to have any side effects at all. I never gained weight, lost hair, felt nauseous, or anything. Then on Halloween 2004, I suffered a moderate brain hemorrhage. I was 21 years old, and very healthy with no prior health conditions. The doctor said he didn't know the cause, I had several tests done, there were no signs of aneurysms (I am not sure of the spelling there) or any AV malformations. He said it could possibly be the birth control, but he can't be sure. I was immediately taken off of the pill and all other birth control pills because of it, and have had no problems since.
