My husband and I are trying to become pregnant. This month is my second cycle off of birth control pills. My first month, I got my period at day 28, jut as I had each month on the pill. It was a very heavy period in comparison to my period on the pill and lasted a full five days as compared to three. The first day of my LMP was July 9th. On July 28th I began to "spot" a pinkish brown discharge. It only occured when I wiped--I never had to wear a pad or anything more than that. This discharge has been intermittant since then...that would be for a total of 9 days as of today. Today is the actual day I suspect my true period should arrive and as of now it has not. Could this still be implantation bleeding? Could it possible last that long?
