Kfc symptoms and conditions

I started taking Yasmin in May of 2006 and all the benefits that they talked about (helps with acne and weight in particular) i experienced. Recently I decided to come off the pill it's been about a month now just last week I started experiencing a few break outs (in the beginning) but now the break outs have gotten pretty bad, last night i had some headaches and this morning when i was to work they were occurring to fast one behind the other at one point i had the feeling as if my period was coming but it didn't and then today at lunch i felt extremely bad and wanted to vomit my coworker came in with some KFC and I could not stand the scent of it. For one brief moment i thought maybe i was pregnant. I decided today to go back on the pill. Didn't have any problems while I was on it.
