... apparently necon is the generic version of cyclafem. I just started taking the yellow active pills on December 26th. I had unprotected sex multiple times with my boyfriend over the course of the pack (including the first seven days in which you are supposed to use a backup method - I did not know that I had to due to it being the same strength and what not as my previous pills). I had bleeding on the third week of my active pills and I am concerned that this could be implantation bleeding. Does anyone have any input? I take my pills every night within a few hours of the same time each night. I have four more days of my active pills and then I begin my white placebo pills and I am supposed to get my period. Is there a possibility that I am pregnant based on that bleeding?
