Yaz and period pain

i have been taking yaz for about a month. i'm not taking it for birth control purposes, but because of period pain and irregularity. i was taking another low-dose birth control on which i had awful side effects of breast swelling, tenderness, extreme moodiness, and a complete lack of sex drive.

so far i haven't had the side effects of my previous pill, but i am definitely moody. i find myself getting upset a lot easier, crying for no reason, and being more aggressive and sensitive about things when i am normally not. i feel very different emotionally on this pill. i've decided to give it one more month and if things don't balance out, i'm going to go off it. what makes me feel worse is this winds up getting taken out on my family and boyfriend, and i don't want it affecting our relationship. also, i am having some sexual side effects, like an inability to physically get "excited" when this has never been an issue before.
