Is this normal?

Andrea

I just started taking Yasmin to treat my PCOS and I've been taking it for 16 days now. The first week, my breasts got really heavy and they were very sensitive but that's one of the normal symptoms. After the breast tenderness went away, I started getting nauseous and I am still very nauseous to this day, I can barely eat and everything makes me gag. I've also been having these abdominal period like cramps, but I'm still like 2 weeks away from my period. (I've also been having diarrhea but I don't know if it has anything to do with the pill because every time I get those cramps, I need to use the bathroom???) Is this normal as my body gets used to the hormones? Should I call my doctor and tell them to change my pills?
