DueDateBloom does one thing — as a due date and pregnancy week calculator it estimates a due date and the current week of pregnancy from the last period, an ovulation date, an IVF transfer or an ultrasound measurement. It counts forward from whichever dating method you choose using standard obstetric conventions — forty weeks from the last period, or the adjusted dating an IVF transfer or an early scan implies — and reports the fetal size and checkup schedule for that week. What follows concerns only that tool and the inputs involved in it.
Practically, all the calculation needs is your dates and cycle details. Typical reasons people open DueDateBloom include seeing which week you are in following an IVF transfer, and in every case the work happens on the visitor's own device rather than ours.
For information, not advice
Nothing on duedatebloom.com is professional advice. What DueDateBloom produces is an estimate of a calculation rather than a measured fact, published for general information and education.
Limits of health estimates
The health calculators use population-level equations. Two people with identical inputs can have quite different true values, which is why a DueDateBloom estimate is not a measurement. These tools do not diagnose, treat, cure or prevent disease. Talk to a qualified clinician before changing your diet, supplementation or exercise, particularly during pregnancy or when managing a condition or medication.
No warranty
On DueDateBloom the key assumption is that you entered a case the method covers. It counts forward from whichever dating method you choose using standard obstetric conventions — forty weeks from the last period, or the adjusted dating an IVF transfer or an early scan implies — and reports the fetal size and checkup schedule for that week. Within that we choose the method and inputs carefully; outside it, and wherever rounding, unit handling or browser quirks intrude, the Site comes with no warranty.
