I have started to bleed 5 days before my period is supposed to start. Its dark and its not a lot. I'm on birth control but forgot to take it for like 3 or 4 days. I had unprotected intercourse about 6 days ago. Should I be worried? If anyone knows what's going on please help!

What you are experiencing is called breakthrough bleeding due to missing the pills. Should you be worried? Probably. You see, for birth control to be effective, one must take it every day at the same time every day.

I'd almost assume a possible miscarriage if the dates of the missed pill were a while ago, however I'd say J_9 is on the ball with this answer (yet again).

Cheers
