Yaar, don't stress too much about the exact date! The NHS calculator is great, it just asks for your last period date and cycle length to guess. But honestly, the dating scan your gynac does will give you the most accurate date anyway.
Listen, don't drive yourself crazy trying to calculate the exact hour of conception. The NHS calculator is standard and works on your LMP, but it's just an estimate. Take care of your health, eat well, and let the doctor confirm it during your scan.
Beta, those online calculators just give an estimate based on your last period date. Traditionally, we elder women count from the first day of your last cycle itself. Just eat fresh ghar ka khana and don't look at screens too much.
I remember obsessively putting my dates in every calculator I found online during my early weeks. It's such an exciting but anxious phase, trust me, I feel you. Just hold on till your first scan, it is magical when you see the actual due date!
Haan na, calculating dates online is so confusing sometimes. I also used that NHS calculator but my doctor later changed the date by 4 days during the scan. It's totally normal, ho na, don't worry.
