I've been taking this for 9 months now and I'm about to throw it out the window. The first couple of packs were tough to adjust to but I listened to my doctor and gave them a chance. For the past 4 months I have had breakthrough bleeding for 2 weeks before my period is supposed to start and then I have a 3 day period. I started taking this because I wanted some relief from my periods and wanted a shorter one. Breakthrough bleeding tho is not something I"m able to deal with much longer. Since they are right before my periods, I feel like instead of having shorter periods, I am having periods that are lasting 2-1/2 weeks. I'm not supposed to start my period for another week and a half, but I'm having some spotting and cramping like my period is going to start at any time. I hate this pill and I'm going to call my dr first thing Monday and see about a change.
