wasn't going to have a period? I originally wanted Seasonal. But my doctor said well it is perfectly fine to not have a period. So I am thinking sweet no menstrual cycle, but I get my prescription filled and it has 28 pills. I know she said I will just have 21 pills. and I will use 17 packs in a year instead of 12. So do I not take my placebo pills. And just take the first three weeks in each pack? I called the doctors office and they never got back to me. I am going to call again tomorrow, but can anyone help?
