I always get confused between weeks and months, my last period was around mid April. The doctor said something but i forgot the exact week. How do u all calculate it properly?
Easiest way is to put your last period date into any pregnancy app, it calculates the week instantly. I used one and it kept me updated weekly. But the scan gives the most accurate dating.
The way doctors count is from the first day of your last period, not from conception. So count the weeks from that date. My gynac confirmed my exact week with a dating scan since I wasnt sure of my dates.
Beta dont worry about calculating perfectly, your doctor will tell you the exact week at your scan. Just note down your last period date and carry it for your visit.
