In June I had to have an induced labor at 21 weeks due to medical problems with the baby. she did not survive. I bled 7-8 weeks postpardum. September 28 was the first day of my last period. it lasted around 9 days. now I have been spotting brown,black,and red lightly but consistently for about 2 weeks. my next period is due in 4 days. I have taken 4-5 tests -as we are trying to conceive and all were negative.
