Going off of the Evra patch..

Jane • Just here for my health like I should be!
When I went off of the Evra patch a year go I didn't have a period for six months. Did anyone else have this type of problem? Is there a way that we can contact evra in order to have them have a warning about possibly causing lack of periods for months possibly years? I had terrible health issues during the six months and still do not have regular periods.
