The general rule is the more estrogen, the less break through bleeding. However, you've already tried 35mcg pills which, while still "low-dose", have more estrogen than other "low-dose" pills like alesse or mircette (20 mcg). I would imagine a pill with 50mcg of estrogen would help (such as demulen or ovcon), but this is a pretty large amount of estrogen and can cause lots of other estrogen-related side-effects (like bloating, headaches, breast tenderness, etc.). Yasmin (30 mcg), while still having 5mcg less of estrogen then what you've tried, is "supposedly" better for controlling break-through bleeding. Although I don't really understand why, I think I would personally try yasmin first before uping the estrogen to 50mcg. Good luck!

Thanks so much for the feedback! It really helps. I still have one more pack of the ortho cyclen. If I still have spotting problems with this last pack, I will ask my doctor about yasmin.
