OMG is this Ocella birth control driving me up a wall?

I started Ocella, generic for Yasmin, a little over a week ago. I have been feeling reallyyyyyyyyyyyyyyy sick for about four days. I just want to sleep, not because I'm tired, but because I feel so ill and I don't want to be awake. What is this strange feeling in my head? It hurts, but I took Tylenol and it really didn't help at all. My are heavy, I'm hungry but food makes me feel worse. Oh, and I feel hot, really hot. I'm getting uncontrollable mood swings and this ain't menopause b/c I'm only 19. What the heck is going on?
