If you’ve been on the IVF journey, you’ll know there’s nothing ‘standard’ about it. Every appointment, every milestone, every date comes with its own mix of emotions. So when it comes to the big one, your baby’s due date, you deserve a little clarity.
Our IVF Due Date Calculator takes the guesswork out and gives you an estimated due date based on your specific treatment dates. Whether you’ve had a fresh or frozen embryo transfer, donor eggs, or donor embryos, our calculator helps you work out when your little one might arrive.
And while your baby might still choose to make their debut fashionably early, or late, it’s a comforting starting point after what can feel like an unpredictable ride.
At Kiindred, we get that IVF pregnancies don’t follow the ‘typical’ road. And so, the IVF Due Date Calculator is made for parents like you, where conception doesn’t happen by chance but through science (and a whole lot of patience).
Most pregnancy calculators assume natural conception, using the first day of your last menstrual period to calculate your due date. That might work for some, but if you know your embryo transfer date, you need a tool that reflects your journey.
Our IVF calculator uses your known IVF treatment dates, whether it’s your embryo transfer, egg retrieval, or donor embryo transfer, to give you a personalised, accurate due date. It’s a small way to help you feel more in control of your pregnancy countdown (and maybe enjoy daydreaming about your baby’s star sign too).
Medically reviewed by Hannah Dahlen, Midwife and Professor of Midwidery An IVF due date is your baby’s estimated arrival date, calculated using your embryo transfer date or egg retrieval date, instead of your last period.
Because IVF pregnancies are timed so precisely (you know the exact date your embryo joined the party), your due date can be calculated with more certainty. You don’t have to guess when you ovulated or when conception happened. Which is kind of refreshing after all the unpredictability of fertility treatments.
Your pregnancy still follows the usual 40-week timeline, but with a clearer start date. That can help both you and your healthcare provider track your progress more confidently.
If you’re tired of googling ‘IVF due date’ and feeling more confused than before, you’re not alone. That’s why we’ve made our calculator as fuss-free as possible.
For fresh embryo transfers:
For frozen embryo transfers (FET):
Check your clinic paperwork for your transfer date and embryo stage because, after months (or years) of treatments, it’s easy for the details to blur together.
Once you enter your dates, you’ll get your due date and how far along you are today-perfect for your planner, app, or just to have in your back pocket.
The IVF timeline is pretty different from natural conception. So, using a standard calculator that assumes ovulation and natural conception can feel a little strange.
An IVF-specific calculator estimates your due date using the dates that matter to your journey – your retrieval or transfer date. Not only is it more accurate, but for many IVF parents, it’s also a little confidence boost in a process that’s often felt out of their hands.
It’s also a small reminder that while your journey might have taken a little longer, you get to celebrate every milestone, including your estimated due date.
And yes, we fully support planning a countdown party if that’s your vibe.
