Frequently Asked Questions (FAQs)

How accurate is this gestational calculator?

+

Our gestational calculator uses standard obstetric formulas based on the Last Menstrual Period (LMP) or Estimated Due Date (EDD). While it provides reliable estimates for gestational age calculation, it is not a substitute for professional medical advice. For the most accurate dating, especially in early pregnancy, consult with your healthcare provider for an ultrasound. Our calculator helps you calculate gestational age by LMP and determine pregnancy weeks with high accuracy.

What if I don't remember my Last Menstrual Period (LMP)?

+

If you don't remember your LMP or have irregular menstrual cycles, you can use your Estimated Due Date (EDD) provided by your doctor (often determined by an early ultrasound). Our calculator can work backward from the EDD to give you an approximate LMP and conception date. This method is particularly useful when you need to calculate DUM or determine gestational age when LMP is uncertain.

Is my personal data stored or shared?

+

No. We are committed to protecting your privacy. Our gestational calculator does not collect, store, or process any personal identifying information. The dates you input for gestational age calculation are processed in real-time and are not saved or linked to any personal data.

Can I use this calculator if I have irregular cycles?

+

While you can use the calculator with irregular cycles, the LMP method may be less accurate for gestational age calculation. In such cases, using an EDD from an early ultrasound is generally more reliable for dating your pregnancy and calculating gestational age accurately.

How is the conception date calculated?

+

The conception date is estimated to be approximately 14 days after your Last Menstrual Period (LMP), assuming a typical 28-day cycle. If you input your Estimated Due Date (EDD), the calculator works backward 280 days to estimate your LMP, and then adds 14 days to that LMP to estimate conception. This method helps calculate gestational age by LMP and provides accurate pregnancy week calculations.
