Re: Can you stop BCP in the middle of a pack?
Its very normal to bleed a couple of days after you stop mid-pack. You are withdrawing hormones from your body, just like happens with the last week of pills, which induces a bleed.
As far as when to start your new pack that is a little more tricky. Did you ask your doctor? If you don't wait for your next real period and start it with this withdrawal bleed, I would definitely use backup for awhile. It would kind of be the same as if you had missed some pills.
