"i am currently on my second month on ortho and it works great. the side effects i have had are: i lost a couple of pounds since starting it, my breasts are pretty sensitive, and i will get occasional headaches. other than it worked great. i followed the exact instructions by starting the pill on the first sunday of starting my period (my period began on a sunday) and didn&#039;t have unprotected sex until the after the 7 days. i started my period on the 2nd green pill and it lasted for 3 days."
