Dear Eliz these are not conclusive signs of any sort for pregnancy. Symptoms don’t come so soon anyway. It’s perhaps fear and nervousness more than anything else, consult a registered doctor about it. But, if the sex was unsafe and you want to be sure - do a home pregnancy test - after 10 days of this act... and then NEVER have sex without a condom.
