I was on this pill for quite some time. (5 years) I am a fertile myrtle! When I got off that pill I was pregnant on the third day. So, I think it worked just great keeping me "protected". I will say that I did not know until AFTER I got off the pill that I think it totally squashed my sexual desire. I was having a really hard time gettin' hot and bothered! But, when I got off the pill I was one horny mama. (TMI?) So, I don't know if that's what you meant by "hormones" but I know that I really liked being off the pill!
