A measurement within 2cm of the expected height is considered within normal range. Your fundal height is still NORMAL. Fundal height can affected by many things...how much fluid, position of the baby. You should be aware that ultrasound estimates of age and size are not very accurate at this gestation and later, so really think about if you are willing to take the risks of interventions based on a test that has a high margin of error.
