Help please

Period was suppose to start today but still no period when I woke up. It’s currently 8:19am where I’m at. Symptoms I have are sore breast, bloating, emotional, I’m actually sick with the flu rn(which has nothing to do with it). But yea still no period or spotting or anything . I’m scared. I really hope I’m not pregnant. Since I did have protected sex 3 times last month with withdrawal without any semen getting near me or in me.
