K.N.
I was on Ortho-Novum for many years. I was on a different one (that had a higher dose) and it made me have morning sickness, so I was put on Ortho-Novum. It was considered a 'low dose' pill. Its not a "new one" though.... I had no adverse side effects issues, but everyone is different.
(I have a friend who was on the Depo shot for over 10 years... I guess your not suppose to be on the shot that long... She developed severe ostioperosis from it. Depo shot is progesterone based instead of estrogen. From what happened to her, I was turned off to any birth control that is progesterone based, including the Merina. Just an FYI.)
