When talking about how far along you are, some of the technical/medical terms can be confusing.
GESTATIONAL AGE: this is the term used by medical professionals to date a pregnancy. This term describes the time since the first day of your last menstrual period or LMP. Ovulation usually happens 14 days after the first day of our cycle, but every body is different, so traditional medicine uses the first day of the cycle because that information is usually known.
FERTILIZATION AGE: this term is used to refer to the time it has been since actual conception or fertilization of the ovum (egg) by the sperm. In a regular menstrual cycle, our ovary typically releases an egg (ovum) mid-cycle. At this point, fertilization is now possible if sperm are present. At fertilization, a new life begins and is considered Day One of Fertilization.
GESTATIONAL AGE WILL BE 2 WEEKS LONGER/OLDER THAN FERTILIZATION AGE.
