"I started Ortho Tri Cyclen Lo 3 weeks ago, for regulating my periods, because I wouldn&#039;t get them for months at a time. It took care of that. It also cleared up my face. I&#039;ve only gotten 1 pimple this month and it went away after 2 days! NO side effects at all. PMS is barely there: no cramps on Thursday (I should get my period on Sunday), only one mild mood swing. I&#039;ve been a lot happier too. My dad and I barely fight anymore because the pill calms me down."
