Question 3

How to submit your ultrasound scan?

Accepted Answer

1. Choose your response speed package from the shop.

2. Enter all information at checkout. Please check your email for spelling errors and if paying by PayPal, that the email is up to date as this is where the instructions on how to submit your scan will be sent.

3. Instructions on how to submit your scan will be emailed to you, this can often land in your junk folder. If you cannot find it please email all of your scan images and videos to submit@nubologists.com. We ask that you send all scan images for highest accuracy along with the exact gestation given on the day of your scan (weeks PLUS days). We are unable to offer our service if you scan is prior to 12.0 weeks please do not purchase a prediction if your scan was in the 11th week. If you have your baby’s CRL measurements please include these. They can be found in your maternity notes.

4. Once we have received your scan images/videos we will begin working on your analysis. Sometimes we cannot offer an analysis and will respond to let you know that we will be refunding.

5. If you have chosen Rapid Response you will receive your results within 30 minutes. If you have paid for fast track we will have your analysis returned to you within three hours. If you have paid for the 24 hour service we will return your analysis within 24 hours. Please do not email us asking when you will receive a response. This will slow your prediction down. 24 hour service on average takes 24 hours. Please only email to enquire on where your prediction is if we are later than the time frame chosen.

6. Your analysis and detailed drawing will be emailed to you. Nothing is posted. We are a completely anonymous service and nothing will be shared across social media without your consent. We are data protection compliant.

7. We do not offer refunds if we are incorrect. None of our readings come with a 100% guarantee, as nothing but birth is 100%. We are renowned for our accuracy and trust worthy service, please feel free to check our reviews on Trust Pilot or Facebook.

Question 6

Why can’t you predict my baby’s sex?

Accepted Answer

In some instances, it may not be possible to predict your baby's sex. This is usually because the ultrasound images do not provide enough information for us to make a reliable assessment.Common reasons include:The genital tubercle (nub) or genital area is not clearly visible.Your baby's position prevents the relevant anatomy from being seen.The scan images or videos are not clear enough for accurate analysis.The genital area has not been captured during the scan.The gestational age is too early for a reliable assessment.If this happens, we will contact you promptly by email to explain exactly why we are unable to provide a prediction. We believe in complete honesty and will never guess your baby's sex if we cannot do so with confidence.As part of our guarantee, if we are unable to assess your baby's sex, you will receive a full refund.To maximise the chances of receiving a prediction, we recommend submitting all of your ultrasound images and any videos available, as different angles and frames often reveal anatomical details that may not be visible in a single image.

Question 7

How accurate is my prediction?

Accepted Answer

Our team consists of specialists in early foetal development, with a particular focus on the dense tissue that develops into the baby's genitalia. With training from experienced sonographers, our years of expertise have earned us an exceptionally high accuracy rate of 99%.

It's important to clarify, though, that we are not medical doctors. While our methodology is well-founded and trustworthy, we cannot guarantee the accuracy of our nub readings.

Our nub readings come with a confidence level expressed as a percentage.

Question 8

Why does gestational age matter?

Accepted Answer

The genital tubercle (nub) develops rapidly throughout the first trimester. Even a difference of a few days can significantly change its appearance, particularly during the 12th week. This is why we always ask for your baby's exact gestational age on the day of the scan. Want to know why gestational age is so important? Read our complete guide: Why Gestational Age Matters.

Question 9

Why can confidence vary between reports?

Accepted Answer

Every report receives an individual confidence rating based on your baby's exact gestational age, scan quality, foetal position, surrounding anatomy and the visibility of the genital area. While our overall historical accuracy exceeds 99% across suitable predictions, each scan is unique and is assessed individually.

Question 10

Why do some boy nubs look like girl nubs at 12 weeks?

Accepted Answer

At 12+0 weeks, both male and female genitalia are still developing. Female genital development generally follows a more consistent appearance, whereas male genitalia often undergo more noticeable changes between 12 and 14 weeks. As a result, some boys can initially display a typical female-appearing nub before developing obvious male characteristics over the following days.

Question 11

Should I wait before submitting my scan?

Accepted Answer

We proudly assess scans from 12+0 weeks, allowing parents to discover their baby's likely sex as early as possible. Many scans at this stage receive high confidence ratings. However, if you would prefer to maximise the likelihood of receiving a higher confidence prediction, you may wish to wait until a later gestation before submitting your scan.

Question 12

Are you receiving my emails?

Accepted Answer

If you’re worried that we may not have received an email from you, you can contact our Customer Service Team on Facebook @thenubologists

Question 13

Can I send another person's ultrasound image?

Accepted Answer

You are only permitted to upload scan images that are either your own or for which you have received explicit permission from the individual involved. By purchasing our services, you confirm that you have obtained consent to share the image with us if you are uploading on behalf of someone else.

Question 14

Where do I send my scan?

Accepted Answer

Instructions are sent via email on receipt of payment. Please ensure the email address that is attached to your payment method is the correct one to contact you on. If it isn't please email submit@nubologists.com with your order number or contact us on Facebook.

Question 15

Will I get a refund?

Accepted Answer

Yes, but only in certain circumstances.If, after reviewing all of your submitted ultrasound images and videos, we are unable to provide a reliable prediction, you will receive a full refund. We will always explain why your scan could not be assessed, whether this is due to gestational age, image quality, your baby's position or the genital area not being clearly visible.As nub theory is a prediction and only birth can provide 100% certainty, we do not offer refunds if your baby's sex at birth differs from our prediction.Refunds are typically processed within 5 to 10 working days of being approved. During particularly busy periods, this may take up to 14 working days.In some cases, our payment team may cancel your transaction before the refund has been processed. If this happens, you may see the pending transaction disappear from your bank statement rather than receiving a separate refund. This is because the payment was never fully processed and the reserved funds are simply released back to your account.Our refund policy reflects our commitment to honesty. We would always rather issue a refund than provide a prediction we cannot confidently stand behind.

Question 16

What payment methods do you accept?

Accepted Answer

We accept PayPal and debit and credit card payments made through our Submit Your Scan page.
