Hi. I'm a 21 y/o female, I take birth control in the daily pill form. I messed up a few weeks ago and took a pill very very late, but within I'd say 6 hours of my normal time. I got an 'old period', meaning very brown and dark blood, that lasted for about a week..now I'm onto regular red blood, really light flow, but it's been going for THREE and a half weeks, really interrupting my life. I've been taking my birth control the whole way through but it's not stopping anything. Help!
