Yasmin and antihistimines

So I started taking YASMIN in December 07. I switched to YAZ in January 08 and just quit a week ago. So about 4 months of bc. A week ago, I broke out in hives and rashes. I would itch one spot and then others would form. The areas get hot and the welts raise up my skin. It started when I was out in the sun but it couldn't have been sun poisoning because I never got burnt. I am diagnosing myself rather than a doctor because they do NOT know everything. After reading into the YAZ and YASMIN side effects, I am not risking anymore problems. Oh and I got an upper respitory infection along with the rash. This lingering cough has a weaze and phligmy sound. My friends are concerned with it too. I have never been the type of person to suffer from any major sickness or skin problem. I am tough skinned and have never gotten any kind of food allergy. I am 24, 5'6'' and in semi-athletic shape. I am an actor and model and I cannot afford to get rashes and a bad horsey cough! YAZ was great for 2 months and now bam! Downfall happening. Temporary relief-cortozone cream and antihistamines like benadryl.
YAZ benefit-clear skin, no PMS
YAZ side effect-rash, no sex drive/libido loss, difficult/no orgasm, appetite like a hog! Food #1 thought. Packed on pounds quick.
YASMIN benefit-clear skin, lost weight quick
YASMIN side effect- a little loopy, speech impediment, no sex drive/libido loss, no orgasm, couldn't even fake an orgasm!
