Probably not, but...: It can be hard to tell if a woman is pregnant because some of the symptoms seen in early pregnancy can also happen in non-pregnant women. A urine pregnancy test gives a reliable result if done correctly. If still worried about pregnancy, one can test about 3 weeks after sex (3 weeks after when conception might have occurred), or 1 week after missing a normal regular period.
