I would definately try seasonale. No there is nothing wrong with switching after trying one. It is true that ortho tricyclen lo is fda approved for clearing up skin. Although most other birth controls do the same, they are just not fda approved and marketed like ortho is. Seasonale will probably keep your skin clear just as ortho did. Again I would definately try seasonale and see how it goes. All seasonale basically is, is a birth control that you take continuously for four months with no break weeks (ie bleed weeks). Potentially you could do this with any type of birth control, simply take it continuously straight through for four months with no break weeks. You don't need to have your period every month while on birth control seeing as how you are not ovulating. When you have your "period", it is simply a bleed period, you give yourself a break from the hormones. I know many women for instance if they know they are going on a vacation, or simply don't want to have their period one month for whatever reason will start their new pack directly after their last active pill and not take the sugar (placebo) pills. I am in nursing, so I am not just some inexperienced person giving you this information. I am not telling you to do this with your ortho tricyclen lo before trying seasonale. Try seasonale and you may find even more things you like about it also. If you are half way through the four months and for some reason don't like it and want to switch you can. You would just treat it as any other birth control and wait a week prior to starting up ortho again.
Hope this helped. Best of luck!
