Hi, I have a question about birth control . I ve been on the pill for about 4 months, I had my last period November 11, and I went to my gyno on the 26th to make sure the pill was working, it was so I decided I d start taking a less expensive generic pill. I was on Generis Fe for 3 months and I switched to Junet Fe. I should have gotten my period any where from December 11-15.. It s now the 17th and I still haven t gotten my period. I ve never missed a pill, and my boyfriend and I always use condoms .. This delay in my period is really freaking me out, and I m not sure if it s from a lot of emotional stress I went through last week or the change in pills. Your help would be greatly appreciated!
