late period SO SCARED

Ladies please I need help or reassurance from someone, my boyfriend and I had intercourse on the 26th of Dec. And used protection, but I can't remember when I got my period last, I remember having egg white discharge about two weeks ago but still no period! I'm not experiencing any stand out symptoms of pregnancy like bloating or nausea but at the back of my mind I can't help but worry! Please help 😭❤️
