Will since December I've been having ultra light spotting for two weeks on and one week off. I just got done spotting Thursday. This last bit of spotting seem really dark in color, almost black. My primary doctor has my thyroid under control last time it was tested it was below 1 so I don't believe that could be the problem but I could be wrong. I'm also in the category for prediabetes. The doctor's office wasn't able to get me in until March 13 which falls during my "spotting week". I plan on keeping this appointment even if I am spotting so that she can actually see what's going on with my body.
Long story short: what could be the cause of my two week spotting and the dark coloring? Have any of you folks experienced this?
