How to know pregnancy days?

Question

I recently found out I'm pregnant, and my doctor asked about my last period to calculate the due date. I'm trying to understand how exactly they figure out the number of pregnancy days and weeks. Is there an easy way to track this myself?

Actually the standard way is counting from your LMP or last menstrual period. But to be 100% sure, a dating ultrasound scan by your doctor is the best way.

Simple hai, don't sit and calculate on your own. Go get a pregnancy kit, do the test, and then visit your gynac for a dating scan.

Arey beta, count from the first day of your last period, that is how we used to track in our times. But ghar pe guess mat karo, go to the doctor and get a proper scan done.

Honestly, those baby tracker apps will tell you your baby is the size of a green pea or a blueberry, haha! Just check with your gynac, they tell the exact weeks.

I am also trying to understand this, it is so confusing! I use a period tracking app which shows ovulation days, hopefully it works for me soon.
