"i have been on yaz for about three years now and i love it. i have experienced great decrease in my pms. i was a monster before starting yaz and now i&#039;m normal with occasional periods having slight mood swings or cramps. my boobs have grown and my acne has subsided. i get a few pimples every now and then commonly when my period comes. i do get some bloating but if i take something like midol then i have none. i&#039;m able to know exactly when my period starts. i have only experienced one occurrence in 3 years of using yaz, of spotting when not missing a pill. i haven&#039;t noticed any weight gain due to the pill. the only thing i am worried about is the scare of blood clotting lately."
