Pregnant ?

My boyfriend and I had unprotected sex on my most fertile day this cycle. He did cum inside of me. I’ve had ever early pregnancy symptom in the book and I’m 10 dpo. I will test in the morning. But if it is negative why am I having so many of these symptoms that are not normal for me. I have sharp right sided cramp that comes and goes. Breast tenderness. On and off nausea. Constipation. Headaches. I am very in tune with my body and feel pregnant but confused if it would be negative.
