telling gender – is there a big difference between 17 and 18 weeks

I don’t think it makes a difference really.  The reason most people find out at their 20 week appt is because that is when the anatomy scan happens to be scheduled to check for all parts of the baby and that appt is so in-depth, one thing they can usually tell you is the gender.  20 weeks is not a magical number for gender though by any means, in fact the genitalia are already formed before this.  I went for an ultrasound at 16 weeks and the tech was able to tell me with 95% certainty I was having a girl.  I had another appointment a week later and that tech gave 100% certainty it was a girl.  Pointed out the labia and everything, it’s not simply absence of a penis anymore.  So really they could tell at 16 weeks for me so I don’t think 17 or 18 weeks will make a difference for you.  Google some ultrasound photos at 16/17/18 weeks and you will see how clearly you can tell gender if your baby cooperates.  Ours didn’t cooperate that well at the 16 week appt but after some shifting positions she finally moved to a spot where the tech could see!  Good luck!

We had an elective u/s at 17 weeks. We had to pay for it but it was worth it because we did not want to wait for the 20 week appt. It was verry clear that it was a boy at 17 weeks.

We actually decided to do the elective u/s because we found a company that offered a gender u/s and a 3D/4D u/s for about the same price as the doctor’s office. We already decided we wanted to do the 3D/4D so we figured it was a good idea to go elsewhere and get 2 u/s for the price of 1. I just looked on yelp for elective ultrasounds in my area and I googled them as well.

as long as its not your officially ANATOMY scan, I would say go for it. I found out at 16+5. You’re def far enough along but remember baby may not cooperate. however if this is for your big Anatomy scan I would push it back because that’s early and they really are doing the scan to check all the baby’s bones and organs and to get the best information it’s best to be a little further along.
