Yasmin and random spots

I'm 27, and have never taken BCP's before.
I've been on Yasmin nearly 4 weeks with few side effects (one unacceptable).

Bad: After 2 weeks on Yasmin, I developed unbelievable scalp itchiness (never before) to the point of wanting to scratch holes in my head. Often. Random spots of amazing itchiness (arms, ears, chest, legs, back, hands) arrived a few days later that rival contact dermatitis in severity. There is nothing else I can attribute this to besides Yasmin (I hope it is not allergy based, as I basically have no allergies).
I've tolerated the itching for nearly 2 weeks, and will give it another 6 to see how it goes. It's not an acceptable side-effect.
Otherwise, I've just gotten slight spotting (skipping placebo pills) and a decrease in sex-drive. Not impressed. I had no sex-drive for 2 years because of a prolactin secreting pituitary tumour. Once that was treated, my sex-drive was amazing. Everyone should be able to feel like that! I'm attuned to that now, and it is diminished. Will give Yasmin a trial though. Sadly a catch-22, since I'm taking it because I've found someone special.

Good (?) side-effect: Oh my god, I've lost my chocolate-drive. I enjoy one chocolate, not most of a packet like I used to. Could not believe this. Hormones are amazing.

Sorry to hear all the serious side-effects posted here. I hope you all find what is right for you. Without quality of life, what is left? Best wishes.
