Hopefully the bleeding will stop by Monday. I'm glad to hear you will be seeing your Dr. And I do think it may have something to do with your birth control. Maybe it's time to try a different one.
I'm not able to get into see the doctor until Monday. So was just wondering. I know that changing pills can cause problems. But it seems very sporadic and heavy which surprises me.
I'm not sure what could be going on. Usually dark or brown blood is old blood. Can you get in to see your Gynecologist? This could be cause from the pill you're on.
