My periods were always a bit irregular so im not sure about my dates at all. Doc gave one number from scan and im getting confused between weeks and months. How do you all keep track exactly?
Doctors always calculate pregnancy from the first day of your Last Menstrual Period (LMP). It sounds strange since you weren't actually pregnant then, but that is the medical standard, so don't worry.
Calculating the exact days is like a math puzzle! Just use the first day of your last period, or let your doctor figure it out during the scan while you prepare for the real chaos.
I felt so surprised when my doctor said I was 6 weeks pregnant when I thought it had only been 4 weeks. They count from your last period's first day, which made me realize how fast things move.
To know the exact days, it is best to ask your gynac during your first dating scan. Online calculators are okay for estimation, but only the ultrasound scan gives the most accurate gestational age.
