Sure, it can happen: A urine pregnancy test, done correctly, gives a reliable result 3 weeks after sex (3 weeks after when conception might have occurred), or 1 week after missing a period. If done sooner, a positive result is likely real, but a negative result may be due to testing too soon, and thus lead to a repeat test. If a woman gets her normal regular period, then she is not pregnant, and a test is not needed.

Some sperm: can be released, even though you withdrew, though this does reduce the risk somewhat. A 20 % chance of pregnancy with ovulation and full ejaculation. Decreased chances, are to quantify, but certainly reduced, but not zero chance.
