Hello! Because I was sick the day I was supposed to start my bc pack, I did not take my first pill -thinking that the first day was not as important, which also led my bf and I to have unprotected sex.

So, here is how it goes: first day: I was supposed to take it but did not.
Second day: took my first pill (and had sex).
Third day: told a friend about the situation and she said that the first day was critical to miss so I took 2 pills to make up for the first lost day.

Will having the 2 pills help my chances of not getting pregnant?
Or did I have to take the 2 pills on the second day for that to work?

Thank you.
