Nope because zany is right.
If you had sex last night then there is no way you can experience pregnancy symptoms yet.
You don't have to come to get a girl pregnant, the penis excretes fluid (natural lube also called pre-cum) which can contain sperm
also we can't ever tell you yes or no if you or someone is pregnant.
So best thing to do is get birth control or preferably stop having sex.
To find out if she is pregnant you'd need to wait until her next period is due and if she skips it then take a pregnancy test.
Better yet go to her doctor and get a morning after pill (these can be taken within 72 hours of unprotected sex).
And please - do not make the same mistake again.
