Depends: Due dates are an approximation they aren't an exact science. Even a 1st trimester ultrasound is no better than about +/- 7 days. So, if her "conception date" is close to your timing of sexual encounter then you need to do a paternity test. A third trimester ultrasound is only accurate within +/- 21 days.
