Frequently Asked Questions
How accurate is the due date calculation?
The due date calculation is based on the standard 40-week pregnancy timeline from your last menstrual period. Only about 5% of women deliver on their exact due date, but it's a good estimate for planning purposes.
What if I don't know my exact LMP?
If you don't know your exact LMP, an ultrasound scan in early pregnancy can provide a more accurate due date estimation. The earlier the ultrasound, the more accurate the dating.
How does cycle length affect the calculation?
Women with longer cycles typically ovulate later in their cycle. If your cycle is consistently longer than 28 days, your due date may be adjusted accordingly.
What are the key milestones during pregnancy?
Key milestones include positive pregnancy test (4 weeks), first heartbeat (6 weeks), end of first trimester (12 weeks), feeling baby move (16-25 weeks), viability (24 weeks), and full term (37 weeks).
