I am taking loestrin BCP and is wondering if smoking marijuana may play a role in this weird discharge that I have. I had a menstrual cycle twice last month and it was black in color the first time n the second time it was the same color but looked like powder. This month, I have been having finish colored discharge for about 3 days and it looks like it had little balls of white tissue in it, and I bled a dark red discharg, about 2 oz, and it looks like powder. The dark red blood isn't in my underwear, but the finish colored is...what should I do? I am 24 yrs, weighing 130 lbs, with a terrible history with contraceptives due to bleeding issues. I've been on the marena, the implanon, and the depo shot and bled heavily on all except the marena.
