US @ 18W-Accurate Gender?
Fri, 11-18-2011 - 9:49am

Based on some of my early ultrasounds, my doctors set my EDD at 4/19.

At 18 weeks, I wouldn't be concerned about inaccurate gender. With DD, I was a day or two shy of 18 weeks and the tech was spot-on (even I could see the "3 lines"). This time, I had an elective at 15 weeks, then the doctor did another just shy of 20 weeks and both had the same gender outcome. Those techs are pretty experienced, and at 18 weeks, the baby is definitely developed enough to determine gender.

For one, here is the only thing I can tell you based off of my experience. The docs always told me the earlier the u/s, the more accurate in terms of predicting the EDD. You're probably safe to go with the 4/19 due date. Also, at my clinic I know they don't change the EDD unless u/s shows a discrepancy of + or - 7 days.

As for 18 weeks, I'd think you'd have no problem with gender determination. I've got at 15 weeks and some days and 16 weeks and some days respectively to find out the gender on mine and it has always been really obvious. You should be fine. They know their stuff! :) Good luck!

I had my u/s at 18wks and 6 days. There is no mistake that this one is definitely a boy. Of course angles and a good view play an important role. But at our ob office their scans are always done between 18-20 weeks and I've heard that at 18 weeks it is pretty accurate from there on.

I would feel pretty secure with a 18wk gender determination! I know many who go have them done at 15wks and, though the further you are the more definite the US tech can say, 18 weeks is a pretty good point because they really are developed down there by then and the techs shouldnt have a problem telling, as long as baby cooperates.
