Sore Boobs 10 DPO

I just started having sore boobs and nipples on the 22nd, yesterday, but it got worse today, the 23rd, and I'm 10 DPO. Tomorrow, the 24th, I'll be 11 DPO. I had sex on the 11th of Septmeber and my OV day was on the 13th, I been having symptoms I never really experienced in this time of the month. And I looked up pregnancy symptoms and my symptoms correlate with the pregnancy symptoms. I just need more advice or some things that other people might think..
