I'm a bit confused about how the doctors calculate pregnancy months. How is pregnancy month usually calculated from the last menstrual period? I want to understand my timeline better.
At this point in my 3rd trimester, I am just counting the days until this baby is out, haha! But yes, doctors calculate from your last period's first day. So technically, you are already 'pregnant' before the baby is even conceived!
I used to spend hours tracking the exact days and worrying if my baby's growth matched the exact week! Doctors use the LMP (last menstrual period) to start counting. Don't overthink the exact day, just trust the scan dates.
Honestly, I still get confused with this! I am in my 24th week and keep googling which month I am actually in. Why can't it just be simple 9 calendar months instead of weeks?
The 40-week calculation is important because it helps you budget for tests like the NT scan and anomaly scan on time. Since doctors count from your LMP, keep that date handy for all your insurance and hospital booking paperwork.
Doctors calculate it from the first day of your last period, even though my MIL counts it differently from the day of missed period! It gets confusing but always follow the doctor's calendar for scans and tests.
I felt so confused initially because 4 weeks doesn't mean exactly one month since months have more than 28 days. When my doctor explained that they count 40 weeks from the last period, it finally made sense. It felt so exciting to track the weeks!
