Need some guidance or help ladies!

I've been ttc for 18 months and I'm 9dpo today. This month I feel different. Women always say they just knew they were pregnant but I'm not sure what I am experiencing. My breasts have never been so sore and tender in my life! This is a totally out of the ordinary symptom for me in the 18 months ttc. Tonight I am experiencing like a burning aching pain all over. The sorest spot are below the nipple and on the sides bear the armpit. Also it seems as though my right breast hurts more then the left. Has anyone ever experienced this and got you BFP?!
