    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 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.

  • Why can’t you predict my baby’s sex?
    In certain instances, analysing your baby's sex may not be possible. This usually results from unclear images, the baby's sex not being captured in the scan, or the gestation period being too early for a determination. Should this situation arise, we will promptly notify you with a courtesy email, explaining the specific reason for our inability to predict, along with a full refund.
  • How accurate is my prediction?
    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.
