I'm on birth control have have been steadily for the past 5 months. As most of you know, on the 4th week of your pack, you take "fake" pills and thats when you get your period. Well, I missed 2 pills because I was away for a weekend. & This was normal to me because when you stop taking the pills, you bleed. But I'm still bleeding 8 days later. I've never bled for 8 days, even off birth control. Any ideas?
