I have been on Lo Loestrin FE for about 5 months and have been consistently getting normal periods on my inactive brown pills. When I finished the last pack, I got my period as planned, but about a week or two into the next packs active pills, I experienced brown discharge when I wiped and then sometimes it was slightly red. It only lasted for a few days. I thought it was just normal breakthrough bleeding, so i didn't think anything of it. But now I am on my inactive pills for this months pack and have not had my period yet. Any reason for this?
