Hellppp

So recently about 1 week after I had unprotected sex (which I ovulated about 2 days later) I started having breast tenderness and soreness on August 11th about 9 days before my expected period which is going to be August 20th. My usual PMS symptoms are breast tenderness however not this early. I check my last 4 cycles and the earliest symptom was of 6 days. They been hurting ever seen. I mostly notice it when I take my bra off because the sides of my breast hurt and they feel a little full/heavy ? Has anyone had this happen to them and get a bfp ??
