Venting starts now: I generally spot brown the day before my period, however this cycle I started to spot day 24 of my 28 day cycle. Okay, not a big deal, I'm sure there could be a number of reasons why this is happening. I mean I did take two intense spin classes two days in a row, my yoga instructor is out on vacation so instead I upped my cardio last week. But the thing that gets me second guessing myself is the fact that Saturday I had one bright spot of red, I mean this thing was smaller than a dime and less than 1% of the rest of the brown spotting from the past four days, yet I can't forget something so out of the ordinarily for my body. So two negative tests and countless trips to the bathroom I'm still wondering...Implantation bleeding or mind games???
