Before my period starts "Flowing" there is always at least a day or three of a brownish/pinkish spotting. Usually it just shows up on the toilet paper after I go to the bathroom. Then I know my period will "start" in the next couple of days. But now that I have started to try and calculate my date of ovulation, I don't know what day counts as my first day of my period. Some doctors say it's the first day you see ANY blood/spotting. Other doctors say it's the first day blood starts to flow. This presents a discrepancy of up to 3 days, which makes my attempt to calculate problematic! Also, if I do count the spotting days, my cycle is really weird.. Because I spot after the flow also. How do I count? I'm trying to conceive but it's really complicated.
