I'm scared

Okay so last month instead of taking the pills i am suppose to take to ft my period I just started the new pack cause I had something planned with my boyfriend. (This is the first pack I've taken since getting back on it) and we did the do and he came inside of me and I've taken my pills before I seen him how I'm suppose to and after how I was suppose to and I'm suppose to get my period today but it hasn't came yet and it's currently 4pm I'm scared out of my mind I really don't want to be pregnant
