How to calculate gestational age after ovulation has receded

However, sometimes a woman's ovulation period may be delayed, which may lead to errors in calculating pregnancy. In this case, how to calculate gestational age?

Gestational age can be calculated in the following ways:

1. Calculate the gestational period and gestational age from the first day of the last menstrual period.

2. If you forget the first day of your last menstrual period, you can calculate your pregnancy period and gestational age by estimating the date of fertilization.

3. If the fertilization date cannot be estimated, the fertilization date can be estimated by measuring the basal body temperature, and then the pregnancy period and gestational age can be calculated based on the change in basal body temperature.

No matter which method is used, the gestational age needs to be determined based on the number of days and weeks of pregnancy. If you cannot accurately calculate your pregnancy period, it is recommended to consult a doctor to ensure that your baby is healthy.
