In the beginning of 2011, I was under a MASSIVE amount of stress due to numerous things. I was late on my period, but figured it was normal because of how stressed and depressed I was. Then, bam. I got hit with excruciating cramps (which I had never had before) and proceeded to bleed for a month straight, finding more bits of tissue than usual in the blood that would exit my body. I was 17 at the time, if that makes a difference. I never went to the doctor, but my step mother said that I was probably having a m/c from the way my symptoms sounded.
