I was on depo for 6 months. I stopped getting the shot 6 months ago. I have had regular periods since then. My period is now 6 days late, I have had render breasts for a month, small cramps but no period. The past two days I have wiped and found a very light brown on the toilet paper, about 3 times. Tonight, I had a very small stringy clot. What could it be?
