Can i be pregnant?

Hi! So I had sex on the 7th, 3 days after my fertile period. He used a condom and pullet out before he cummed so I could give him a bj to finish the deed to avoid any loose sperm. I have been feeling naseous but I do not know if its because of nerves since I know it may be too early for symptoms. How likely is it for me to be pregnant and when can I take a test?
