Started new bc pill pack 2day. had unprotected sex 2day. period was supposed to end yesterday. started bleeding a little after sex, normal? protected?

It may be normal: As long as you are taking bcps as directed, there should be no problem . And it may be normal.Yes you are protected if you have been taking the pills as directed.

Depends: When was the last time you took pills? If it was a week ago, you probably are protected, but no guarantee. If it was longer than a week, you're not protected. If you want more reassurance, take a Plan B (it's over the counter) or make an appointment to see a doc in the next 4 days to get a copper iud placed.
