I started this months cycle on april 11, 2017. This cycle only came out when I went to the bathroom. It was a normal color and then became brown a few days later and continued to only show when urinating.. Around April 17 and 18 it stopped. Today is April 21 and as I urinated it came out again but a little bit more of a maroon color similar as if I started my cycle again. In between the times of April 11 til now, I have a slight cramp on both sides of my abdomen. Is there something wrong I should worry about?
