Ultrasound.: Is by far more accurate than dates, especially if you have irregular menses. Women ovulate on different days, especially when cycles are not clockwork regular. There will be another US done later on, but for now it is safe to assume that your fetus is closer to 5 days younger than your date suggests. Remember, lots of women give birth earlier or later than their expected date. Focus on healthy!
