I'm trying to accurately calculate my due date and track my pregnancy. Can someone tell me which day is generally considered the 'first day' of pregnancy for calculation purposes? Is it the last period or conception?
It's counted from the first day of your last period! It sounds so weird, right? I was so confused when my gynac told me I was already 5 weeks pregnant when I had just missed my period.
Haha, doctors literally count the weeks when the baby wasn't even there yet! It starts from the first day of your last period. Enjoy those 'phantom' weeks of pregnancy because the real sleepless nights start soon!
Medically, the first day of your last period is counted as day one of pregnancy. Since my cycles were so irregular with PCOS, this calculation was a bit off for me and the doctor adjusted my due date during the first scan.
I completely understand how confusing all these medical calculations can be! Yes, they count from the very first day of your last period, even though actual conception happens about two weeks later. Don't worry, your doctor will explain it all gently.
Haan, doctors always count from the first day of your last period. My MIL was so surprised when she heard this, she said 'but how is that possible when conception happens later!' It's just the medical standard.
