How to determine pregnancy due date?

I just got married and we are planning to start a family. My friend told me about calculating the due date. How exactly do you determine the pregnancy due date?

Yaar, usually it's calculated from the first day of your last menstrual period (LMP). You add 40 weeks to that date. Or if you know the conception date, you add 38 weeks. But actually, doc finalizes it after the first ultrasound, which is more accurate.

For many, especially if cycles are regular, it's 40 weeks from the start of your last period. But with PCOS, my periods were irregular, so LMP wasn't accurate. My doctor used the first ultrasound for a more precise date. It's always best to let your gynaecologist confirm it, they know best.

Yes, the LMP method is common, but ultrasound gives the most reliable due date. Trust your doctor's assessment.

They mostly use the date of your last period and then confirm with an early ultrasound. Regardless of the due date, it's really important to keep up with all your antenatal checkups. A healthy lifestyle and regular monitoring are crucial throughout, especially with any existing conditions like high BP.

The main way is usually adding 280 days (40 weeks) from the first day of your last period. Once you know, make sure to plan your diet well. Focus on nutrient-rich vegetarian food for a healthy pregnancy, lots of greens and lentils.
