I wrote on her back on December 11 after a condom break. I`m hoping someone can shed some light on my situation. The day after the condom break I started my period, but to be safe rather than sorry I went ahead and brought/took the generic brand of Plan B (Next Choice One Dose). My period is normally 4 days long but last month it lasted 7. Probably due to the pill. But this month I have yet to get my period. I have taken a sensitive pregnancy test and got back a negative. I`m panicking and need some answers. Anything is better than not knowing what`s going on. Thanks.
