Hello, my question in regarding my menstrual cycle. Last month I got what could have been my cycle, however it was only 2 days long and was a very dark brown color. This month I got the same thing but this one is almost black and the consistency is very thick and sticky. I have stopped taking my bc pills for about 4 months now and my husband and 1 have been using other methods of contraceptives. Should I be concerned or would change be due to me stopping the pill? Thanks
