Anonymous Hi! I am a little concerned..my boyfriend and I had sex on a night I missed my pill, which I know since I doubled up the following day my chances of getting pregnant do not change much. However, 4 days later, I began getting a brown discharge which is not normal for me. Could this be from missing the one pill? Or what are the possibilities of it being implantation bleeding? I took a pregnancy test which came back negative...but isn't it too soon to tell considering my period doesn't begin for another 11 days? Thank you for any help!!
