Birth Control Q's

Megan
HAS ANYONE EVER GOTTEN PREGNANT AT THE EARLY STAGES OF HAVING THE PILL? Say, less than a week in?
WHEN IS THE RIGHT TIME TO BEGIN HAVING UNPROTECTED SEX AFTER TAKING THE PILL?
I have just recently been put on Levlen ED which is an common form of 'the pill'
I have been on them for 4 days now.
I had sex with my boyfriend today and we said it would be okay for him to cum inside me.
I then looked it up after and it says that you should wait a few days after starting before having unprotected sex...
