I recently ran 2 pill packets together. During those 2 months I had interiors twice with the use of a condom also. This month in my week off the pill my period started right on schedule but was a lot lighter ( filling about half a regular tampon in about 5 hours or less). I'm on Yasmin birth control. It lasted for the usual 4 days with extreme light spotting on the 5th which is normal for me. After reading about implantation bleeding I'm do worried! Help! The bleeding was more brown with red.
