so my cycles lately have been 25-27 days. my last "period" started on day 21 of my cycle. it was light pink, but it did last for several days. I just don't feel like it looked like my period at all, I didn't have my usual symptoms like tender breasts, cramping, or irritability before I started bleeding. and usually when my period ends I have brown spotting for several days after, like almost a week. I literally had no brown spotting at all. do you guys think this could have been implantation bleeding or just an early period because of high stress?
