"i&rsquo;m almost done with my second month of yaz and it has been really tough. i was put on birth control for pcos as a way to regulate my hormones and period. both months about three weeks into the pack i get headaches, nausea, upper stomach cramps, exhaustion, throwing up, extremely sensitive breasts, horrible uterine cramps, sporadic facial hair growth (i have facial hair due to pcos and i was hoping yaz would reduce it but it seems to make it grow faster during certain times of the month), and a terrible liquid yellow diarrhea (tmi i know). i&rsquo;m trying to stick it out but honestly i don&rsquo;t even know if this pill is helping with my hormone but we&rsquo;ll see."
