"i have been on yaz for 3 years now and it really helped with a lot of things. my mild acne cleared up and i have beautiful skin, and before yaz i had very irregular periods that would last for 2 weeks at a time. yaz controlled my period and i only have it for about 3-4 days and it is very light. i do get moody while taking the white pills (last 4 pills) and i hate everything, but i&#039;ve always been like that and it only lasts a few days. it has helped a great deal in preventing pregnancy, since i don&#039;t always use condoms. i would definitely recommend this pill."
