My daughter has 3 sons, and really wanted a daughter. When she was pregnant with her 4th child, she did a genetic test that was supposed to show the sex of the fetus (out of curiosity; she had no thought of terminating her pregnancy whatsoever!). She was disappointed but resigned to raise another boy when the test results indicated male. She was ecstatic when the ultrasound revealed her daughter. She was told the false test results reflected the fact she had carried her 3 sons.
