How to calculate gestational age based on ovulation period

First, we need to understand what ovulation is. Ovulation refers to the time when a woman’s egg is released from the ovary and waits in the fallopian tube for fertilization. Generally speaking, a woman’s menstrual cycle lasts 28 days, so ovulation usually occurs between the 14th and 20th days of the menstrual cycle.

So, how to calculate gestational age based on ovulation? We can use the following methods:

1. Calculate gestational age using the periodic table

The periodic table is a tool for recording a woman’s cycle and can help us calculate her gestational age. We can divide pregnancy into 4 stages according to the time on the periodic table, namely pre-pregnancy, early stage, middle stage and late stage. At each stage of pregnancy, we can calculate gestational age based on a woman's menstrual cycle and ovulation period.

2. Calculate gestational age using ultrasound

Ultrasound is another common method that can help us calculate gestational age. Ultrasound can detect a woman's embryo and fetus and determine her gestational age.
