My doctor told me I'm a certain number of weeks pregnant, but I'm a bit confused about how they calculate it. How exactly are the weeks of pregnancy calculated, starting from which point? I want to understand it properly.
It can be so confusing to track, but yes, it starts from your last period's start date. I remember looking at my tracker apps every week, watching the baby grow, it is such a beautiful phase.
I am trying to understand this too because we are planning. It's calculated from the first day of your last cycle, which is a bit confusing but that's how doctors track it.
I was so confused about this at first! They start counting from the first day of your last period, which feels so weird because you weren't even pregnant then. Do doctors always go by this or does the scan change the date?
They always count from your last period's first day. Since I had thyroid issues, my doctor tracked my weeks very carefully with regular ultrasound scans to check the baby’s growth rate.
Oh, I spent hours researching this because my scan date and period date didn't match! Usually, they calculate from the LMP, but if the difference is big, the doctor relies on the early ultrasound. Don't worry too much about it!
