The Baby Due Date Countdown is a date planner. Enter the last time this happened and how many months you usually leave between checks. We add that interval and show the next due date and how many days remain. It does not book an appointment, decide NHS eligibility, or replace your GP or a screening programme.
Enter the last date from a letter or appointment, then the interval you actually use.
The Baby Due Date Countdown is a date planner. Enter the last time this happened and how many months you usually leave between checks. We add that interval and show the next due date and how many days remain. It does not book an appointment, decide NHS eligibility, or replace your GP or a screening programme.
It adds months to a date you already have so you can see the next baby due date countdown date. It is diary maths, not a diagnosis and not an invitation.
No. Book with your GP practice, NHS App or the number on your last letter.
Contact the practice or programme. Do not wait on this page.

The useful output is a date, not a verdict. If the baby due date countdown is overdue, phone the practice. If you never had this check and think you should, ask them rather than inventing eligibility here.
Guidance only. Calculations run in your browser. Numbers are estimates, not a diagnosis.
Last date plus the interval you type, then a lead-in day count. Today is compared with that next date.
