About 9 days ago I missed one pill out of my birth control pack (orthotrycyclen), I didn t realize until the next day, so I just continued taking the pack again as I normally have been at the same time every day. I have had bleeding that is just as heavy as my period, and even a bit of clotting, in the 9 days since I missed my pill. What could be causing this and what should my next step be?
