How long after a woman is pregnant can she find out what gender baby she is having?

A woman can have an ultrasound to determine the baby's sex as early as 15 weeks. However, an ultrasound is not 100% accurate - the only way to be 100% accurate is to have an amniocentesis, which is a risky procedure that a doctor won't perform just to determine the baby's sex.

How accurately can an ultrasound determine the date of conception?

Ultrasounds measure the size of the fetus to predict a due date and are usually very accurate, within two weeks, so I would safely assume that it would not be off by five weeks. You can ask your doctor, it won't be the first time he or she has answered that question,I promise. Also it depends on when the U/S is. U/S before 12 weeks of pregnancy are very accurate, plus or minus 2 weeks. After that there are more varibles, babies grow at different rates so they are not as accurate.


What is the appropriate month to have an ultrasound check up in order to determine the baby's gender?

Usually at 20 weeks which is about 5 months along. But nowadays with high-tech ultrasounds they can determine the sex in as little as 12 weeks, although they usually do not tell you this because at that stage it is very easy to make a mistake.


If your doctor said you were 20 weeks and 4 days at your 20 week scan 10 weeks ago how accurate is that guess You had sex with 2 men 3 weeks apart so are you 30 or 33 weeks?

Ultrasound is very good at aging a pregnancy it is not a guess. 30 weeks. get a blood test with the culprits after the baby is born to determine the father.


What if you hear the babys heartbeat at 4 weeks?
