Hello,

So I'm only taking birth control pills for less than 21 days, yet. One of the days I messed up, I had unprotected sex and I took the plan B within 24 hours. I kept taking my pills as usual. Now, right now there is only 5 pills left so finish the pack and I started bleeding. Like it was my period. What's going on??? Is it normal? Should I stop for seven days like normally I would do ? Thanks in advance...
