"i am almost 25 years old and have been taking yaz or beyaz for the past 4 years. i was diagnosed with endometriosis when i was 14 and have tried various other birth controls with no relief of my endometriosis. when my doctor prescribed yaz i was hesitant at first because of the commercials talking about blood clots but decided to try it anyway. yaz and beyaz have literally been life savers for me. i used to have cramps so bad i was unable to attend school or work. my periods would also be a full week long and heavy bleeding the entire time. since getting on yaz i do still have some cramping but it is manageable with midol. my periods are now 3 days long, with only one day that&#039;s heavier. i don&#039;t have any complaints!"
