My last period date was noted but I still get confused when apps show weeks and days differently. Scan also showed a slightly different week, so now I don't know what to tell relatives. How do you all count your current week?
My gynac explained the week is counted from LMP, the last menstrual period start date. An early ultrasound gives the most accurate week if ur cycles are irregular. Ask at ur next scan.
Easiest way is count from the first day of ur last period, that's how they calculate weeks. I just put that date in a pregnancy app and it showed my week instantly, super handy.
They count from ur last period's first day, not from conception. If ur unsure of dates, the dating scan tells u exactly. Mine corrected my count by a few days actually.
