You mentioned that you're 18 weeks along, and you're just sure that you're pregnant with twins, but when you went to the doctor to have an ultrasound, they only saw 1 baby, and you're wondering what is the chance that they could be wrong. Now there aren't necessarily stats out there for that, but I can tell you, after being a Labor & Delivery nurse for 9 years, I've only seen 1 situation where twins were born where they weren't previously diagnosed. And this is due largely to the fact that we have good technology these days and good screening routines. So of course if someone is doing an ultrasound that isn't well-trained and isn't expert on ultrasounds, then it could be missed.

But it's unlikely, because at that point in pregnancy especially, when they put the wand on your belly, those 2 babies would be easily seen. It's easier to miss when a baby is much farther along in pregnancy and bigger, because then if you find a head, and a heart, and some limbs, and you didn't know about a twin pregnancy prior to that, you're really not looking for anything else, and at that point the other twin could be hiding or something. But again, at 18 weeks it would be pretty obvious. They would be able to see the 2 babies right there on the same screen.

Now if you want, you're more than welcome to seek a second opinion. And in fact, if you are highly suspicious, it would be best for this diagnosis to made sooner rather than later, because if you are pregnant with twins, that puts you at high risk, and you need to make sure that you're seeing a high risk OB doctor. And they'll probably even refer you to other specialists called perinatologists who watch you more closely over the course of the pregnancy. You're at higher risk for preeclampsia, and gestational diabetes, and many other things that they'll be careful to watch you for. So of course it would be helpful to know if you are pregnant with twins.

If by some small chance twins were missed, and you came to the hospital and delivered, they delivered one baby just expecting the one, and then a second was coming, they would just deliver that baby too. And I bet there would be many shrieks of surprise and tears of joy. I hope the very best for you, and if you have any other questions for me in the future, feel free to ask them on our Facebook page at [ Ссылка ], and recommend us to your friends and family too.
