1 week before my period, I had sex. Condom failed. I took Plan B in less than 1 hour.
I am at my period [I think I'm paranoid: I feel like it's bleeding less]. In 4 days, I want to start birth control pills. Might I be pregnant? Is it safe to take the pills if I'm unsure?
[can I be pregnant at all?] - I'm 36.
