Hi, I have been on estrostep and ortho-try cyclen (generic trinessa) for several years off and on. I started the trinesssa again about 5 months ago and have had problems with breast pain and depression/irritability. My dr. switched me to levlen (generic levora I am guessing, haven't got it filled yet). Has anyone had any experience with this? I have never taken a monophasic, just triphasic. DO you have more luck on the mono? Any input would be appreciated. Thanks :)
