"i&#039;m 19 and i had never taken any birth control before yaz. it completely cleared up my acne and my breasts significantly increased in size but were very sore all the time. i had no noticeable weight gain or hair loss/growth or spotting. my sex drive was bipolar, however, and taking the pill also gave me occasional slight dizziness, yeast infection, moodiness, anxiety, and even depression which i had never experienced before. i often had intense headaches and stomach aches but no nausea. my period didn&#039;t seem to get any lighter or shorter and pms, though typically not much of an issue for me, was no different. i got to a point where i just felt awful and had to stop taking it after about 3 months."
