I have been having what i think is implatation bleeding since like midnight Oct 1st. I used the bathroom and saw some light pink spotting. Its been like this since today Oct 3rd. It comes and goes through out the day. Very light cramping doesnt last if any at all. Yes had intercourse multiple times a week before this started. AF due Oct 13th. Once a day usually in the morning it will be a little red but then goes back to pinkish then brown. I read it only lasts few hours to 2days and its goin on day 3 now. Feels nothing like a period, least to me. Cramps r usually more painful and knocks the breath out of me. I need help to figure out if it is implantation bleeding or just a very light period.

Thanks
