Can I have pregnancy symptoms just after 3 days of unpertect

I had sex three days ago and we were wanting to try to have a baby. I want to be pregnant really bad and would like to know if there is a possible way I could have symptoms after just 3 days of having sex? We did it one time and I really want to think that one time can do it for me. I have been pregnant before from one time and had an abortion. Dose this mean that the chances are high for it to happen again with me? I am 20 and i have been having chunks in my throught and feeling nasiated but not throwing up and my stomache feels very tight. I have also been peeing alot more latley. Please let me know my odds cause I really want this to happen.
