I know implantation does not happen to many women, but I am confused about what should be my period. I use birth control, but this month it has been a little messed up and my boyfriend and I mainly do the pull out method. For the record, I plan to take a test regardless in a few days, but still would like some opinions. My period was a day late and has not been normal. I’m on day three and it has been EXTREMELY light and a peachy color. I have also not had cramps as bad. However, when I looked up implantation bleeding it said that it should usually start before your expected period. What do you ladies think?
