Which sonogram is more accurate 7 or 18 week For example at 7 weeks you were 7 weeks and 3 days At 18 weeks you were 19 weeks 7 days Which is correct?

Because an ultrasound at 7 weeks and one at 18 weeks use different methods for estimating gestational age, they have different levels of accuracy. In general, a skilled sonographer's 7 week ultrasound is more accurate for dating than a skilled sonographer's 18 week ultrasound. Talk with your health care provider for information specific to your situation.

Can you tell the sex of a baby at 16 weeks and if so how right will it be?

Yes, you can tell the sex of a baby at 16 weeks, and it is close to 100% accurate. But a few factors will determine whether or not you can see the gender at 16 weeks. The baby's position and the mother's weight determine if you can see the gender clearly. With heavier women, it is harder to see a clear picture of the gender. Some women decide to check for the gender at 18-20 weeks for a more accurate ultra sound.

The ultrasound dating has excellent and precise estimation of gestation especially if done in the first trimester (first 12 weeks). After 12 weeks, its accuracy goes down. However, compared to dating according to menstrual cycle, the ultrasound would be more accurate.
