Oh, I used to get so confused and panicked about this! It's actually calculated from the first day of your last period (LMP), not the day u conceived. Don't worry, your doctor will calculate the exact date during your first scan anyway!
Aap simple period tracking apps use karo like Flo or any pregnancy app. Just enter your last period date (LMP) and it will automatically calculate your due date and weeks in Hindi or English, it's super convenient!
Don't rely solely on manual calculations if you have irregular periods. Since I had early complications, my gynac advised that an early ultrasound (dating scan) is the safest and most accurate way to find the real due date.
I am in my 5th month now and initially, the app due date and scan due date were different, which made me so anxious. Did anyone else also get two different due dates from their doctor and app?
Calculations simple hain: aapke last period ki start date se count hota hai. Usme 9 months and 7 days add kar lo, wahi aapki expected due date hogi. But actual confirmation scan se hi milti hai.
