Is Frequent Urination Post Having Unprotected Sex A Sign Of Pregnancy?

I had unprotected sex about 2 weeks ago and he did the pull out method. I was not ovulating at the time. Now lately I seem to be having to go to the bathroom more frequently. It doesn't burn or hurt and its not every day. Could this mean Im pregnant or did sex just cause me to have to pee more? I don't seem to be having any other signs of pregnancy but it isn't time for my period yet so I have had one or missed one.
