What Causes Headache And Nausea?

Hello i am on the first cycle of YAZ Pill, only two to go and the side effects have been unberable. Too many constant head aches , nausea , irritation , cramps , really tender and swollen breasts , moodswings etc. These have been going on for the past 3 weeks .I heard there is a test i can take at the hospital that would determine which is the right pill for my body . In the meantime until the appointment do i stop this pill after the first cycle finishes?

I wanted to go on the pill to control my hormones. During ovulation and right before the period my whole body changes especially really itchy face/rash. Or would hormone tablets work out better to control my body at that time of the month ?

Thanks
