Risk?

Ellie
So I'm on the pill and I took the last one today but I took it three hours late. I then had sex about an hour later and my boyfriend came inside me. Firstly, I know because i took it late, it's risky. But do you think to be on safer side. I should take one pill off another pack tomorrow and then after that not take anymore for 7 days? Can anyone help or give any advice?
