Which IVF due date calculator is the best?

07 Jul Which IVF due date calculator is the best?

IVF due date calculators are, by definition, happy creatures. Often used by couples after a successful IVF cycle, they estimate your due date based on two days only you and your clinic know: your egg-retrieval day and/or your embryo-transfer day. Try our very own IVF due date calculator here.

Are there any other IVF due date calculators out there? Yes, and they vary considerably in quality and reliability. None are a substitute for professional medical advice and diagnosis. Every pregnancy is, after all, different. And you’ve got less than a 5 per cent chance of giving birth on your due date anyway.

This Canadian IVF due date calculator is pretty good. Just use the drop down box to insert your egg-retrieval/ovulation date and click ‘calculate’. The results give you a useful snapshot of key dates in your pregnancy, including trimester breakdowns and touching moments – such as when your baby first sucks its thumb. It’s a nice little interface.

Another good IVF due date calculator is published by IVF Connections. This one doesn’t give you the cute pregnancy milestones of the Canadian site. But you get a wider choice of dates to key in. You can select the first day of your last period (best for non-fertility patients) and your egg-retrieval or embryo transfer day. This covers all bases if your memory’s hazy.

The due date calculator from Your IVF Journey is designed to be simple, quick and intuitive. Our patients kept asking for this, so we finally built one! It works for all fertility treatments: IVF with own eggs, donor-egg and donor-embryo cycles, and FETs. That’s rare. Results are displayed for singles, twins and triplets in a stylish box.

By contrast, the calculator from BabyMed is perhaps a little clunky. It’s probably used more extensively for regular pregnancies because there’s only one IVF-specific selection in the drop-down box. The IVF-transfer option seems to default to a three-day transfer because the due date displayed is two days later than the other due date calculators we tried out. You’re better off putting in the ovulation date (e.g. egg-retrieval day): it then works fine.

Finally, our round up of IVF due date calculators must mention the humble offering from the IVF Infertility website. This one does differentiate between day-three and day-five transfers, alongside LMP and egg-collection days. No other information though, so it’s best described as cheap and cheerful.

So there you are: add a date and diarise when your life will change forever. (Or perhaps, as an IVF patient, your positive pregnancy test was the day you’ll never forget?) Which is the best IVF due date calculator from this lot? We’re far too modest to say. Good luck and happy calculating!
