I'm 17 weeks, got the gender test a few weeks ago and found out I'm having a girl. But I was so so sure I was having a boy. This is my second baby. Just wondering if anyone has had it turn out to be wrong?

Gender Blood testing is never wrong.  Is the most accurate gender test you can take. So If they told you you're having a girl, then that's what it is,   Doctors make mistakes often with Ultrasounds those should not be trusted 100%.

So I had my ultrasound yesterday and it is a boy!! So the test was right. The genetic counselor explained to me that test looks for Y chromosome in the mothers blood. Since the baby's DNA is mixed in mothersblood during pregnancy, it will detect the baby's sex because the mother only carries 2 x's since she is female. If there is only x's present baby is a female and if it detects a y it's because the baby is a male. Hope I explained that right lol

I had it done a few weeks ago and it says a boy, we thought for sure it was a girl. I go in for my 20 wk ultrasound on Tuesday the 16th and will let you know if it was right :)

99%

I'm pretty sure the blood test is like 99% -100% accurate because they pull the X or Y chromosome to determine the gender.

For my mom's whole pregnancy they told her I was a boy and was 100% sure and I came out a girl. But that was also 20 years ago but mistakes always happen but not quite as often
