Wrong dates!: The most common reason for suspected fetal microcephaly is erroneous due date assignment. If microcephaly is real, it could be part of several fetal syndromes with poor neurodevopmental outcome, such as aneuploidies (down), perinatal infections (toxoplasmosis, rubella, cmv), or metabolic disorders.

As answered, plus: What's important is to have at least 2 more measurements to determine velocity of head & body growth. Any measurement <5th %ile means there's a chance of a problem, but it doesn't tell you if the problem is fetal, placental or maternal. If you didn't smoke, drink or use drugs from the date of conception ( not from date of pregnancy diagnosis) , you've done nothing to cause this.
