My Doctor put me on YAZ, and have suffered terrible side effects... Should I stop

[Spiria]

taking it? He put me on YAZ to get my period up and running again after I was diagnosed with polycystic ovarian syndrome, and it worked to get my period back, but now I'm constantly bitchy, depressed, tired, over emotional, I spent this summer exercising my butt off (No Pun intended) and lost 30 pounds, But now that I've started YAZ (Going on a month and a half) I've gained AT LEAST 15 back (just in the stomach and breasts), I have an increase in appetite, Have horrible headaches whenever I stand up, feel nauseous all the time and just feel like general shit... I have heard that it'll take some time for my body to adjust to it, and some have gained weight and lost it quite easily and naturally, it hasnt really cleared my face up, as acne hasn't been an issue for me. But, what I want to know is should I just quite this birthcontrol and go on a different one, or ride it out? I dont want to just stop birth control because of my P.O.S, as I kind of NEED my period... I just want to know opinions or personal experiences, and what I should do.
