My gynac counted my weeks from my last period date and it confused me thoda, because conception happened later na. Why is it done this way? just want to understand how my due date was calculated.
My doctor explained its because the exact conception day is hard to pin down, but the last period date is something we usually know. So they count from there as a standard reference. The early scan then adjusts the dates if needed, so it all evens out.
Its just the standard medical way of dating, since ovulation timing varies but periods are easier to remember. Confused me too at first. The scan confirms the actual weeks anyway, so I just trusted my doctors final dating.
Yeah its funny na, you are counted 2 weeks pregnant before you even were haha. I argued the math with my husband for a week. Doctors just use a common starting point, dont overthink the maths.
