Early gender? Stephloveslynden Due August 2 (boy); 2 kids; 1 angel baby; California 24423 posts
17th Jan

I just posted this to another forum I'm on but I figured I'd ask here. This baby will be my third and I always thought you couldn't tell the gender before 15 weeks. Also in my previous pregnancies the only way to know the gender was via ultrasound or amnio (or by giving birth lol) but now I hear there's a blood test? There seems to be a very large number of women on this other site that I'm on that are finding out the gender at the 12+ weeks. Is this for real? Is that even accurate (assuming they did not have a blood test or amnio done)? Is there some new technology I don't know about?! I found out with both my girls at 17 weeks but I was so nervous to trust it even then. I can't imagine going to the doctor next week and having them tell me the gender, I don't think I'd believe them!

No you can't find out via ultrasound then. You can do nub theory which is 90% accurate (in my mind) but it's really not accurate until 13 weeks. I'm in school to be a u/s tech.

There is a blood test that tells with 99.9% certainty gender as well as Down's syndrome. 
Also there are signs someone with a trained eye can look for on sonogram at 12+ wks (angle of the dangle). 
I was told gender at 12w6d with my 3rd child and 13w3d with my 4th at my nt scan (sonogram to look for downs markers) Both times the tech was correct.

I seriously offended/pissed someone off when she posted that the tech told her she's having a boy at 12+5 and showed her "boy" parts. I was like "That's called a nub, all babies have it. It's not a penis yet." She told me the tech told her FOR SURE. IDK maybe the tech was using the nub theory? I do know a girl who was told at 14 (? I think?) weeks she was having girl based on the nub theory and it turned out to be wrong, she had a boy. Is the earliest you can find out via ultrasound still 15 weeks? I'm considering doing a 3d u/s at 16 weeks but I'm scared lol.

Yes it's very accurate.  You actually have some of the baby's blood in your blood so they are able to look at the baby's chromosomes via blood test.  The tests I know of are called MaterniT21, Harmony and Pandora.  Some OBs are offering them to their regular patients but usually they're only offered in high risk cases.  I'm high risk but insurance requires an $800 copay. Surprised  Those tests all check for a Y chromosome.  If it's present obviously it's a boy.  If only X chromosomes are present it's a girl.

That makes sense because I've heard that before but they aren't looking for actual PARTS at that stage right?

What is the blood test? It is the harmony one? I'm so confused because I've never heard of this stuff lol. I do the integrated genetic screen for downs syndrome (the blood test plus the NT scan) but unless something changed in 4 years it doesn't tell you the gender.

When I had Hope (15w5d) she was obviously a girl but you could tell where her clitoris had once looked like a penis, only it was pointed way down.  I think the angle of the dangle is pretty accurate but I've yet had a tech try and guess for me. Unknown

I would trust a blood test but not an ultrasound until closer to 20 weeks, I had one at  14 weeks and was told FOR SURE it's a boy, and it clearly looked like a boy but I didn't believe it until I had another one done later.

Well I'd trust a blood test for sure. Thanks for explaining it. It's similar to the amnio then looked for the chromosomes. I get that. I didn't realize they had a blood test but maybe they didn't the last time I was pregnant. I'd definitely trust a blood test but I'm confused on the ultrasound thing.

I would honestly wait until 17-20 weeks so you can be more guaranteed. At around 12+4 the nub starts to rise or stay flat which tells if it's a boy or girl but only from the side and sometimes it's tricky to get a good shot.

My son was obviously a boy at 12w6d. Penis and scrotum in his potty shot.?

With my 4th (current pregnancy) after I was told girl at 13w I had an elective sono at 15w4d and was told boy. I had my doubts (looked like a swollen girl) and I was right :) Id try to wait til 16wks because its easy to mistake swollen girl parts/receding nub with a penis, especially if the person doing the scan isn't experienced or well trained.

Yeah they're fairly recently coming into use.  I had never heard of it before my last pregnancy when a woman in my DD group got the MaterniT21 test and knew the sex of her baby before 10 weeks.

er. 


At that stage, I'd believe a boy over a girl for sure. It's hard to mistake a penis but it's easy to miss one from what I see online lol. If someone told me at 14 weeks I was having boy I'd believe it (and I'd be thrilled lol) but I'm just so confused. I'm not even kidding I saw maybe 5 posts (on another website) in the last couple days from women around 12-14 weeks announcing the gender based on the ultrasound. One girl did say she got the blood test so I feel like she's ok to go celebrate lol.

I believe they've only been offered in the us for less than a year. My ins only covers it if you are over 35 or have positive markers on your nt and quad screen.

I'm 40 and if I were to miscarry after 12 weeks I'd have to have a c-section, so you'd think mine would be fully covered.  I generally have great insurance but they fail in this department.
