Dating age formula for women
The date of the first documented positive pregnancy test and the beta-human chorionic gonadotropin (b HCG) level may help ascertain the minimum gestational age.
In women who conceived following assisted reproduction techniques, the date of embryo transfer is known and may date the pregnancy accurately.
The estimation of pregnancy dates is important for the mother, who wants to know when to expect the birth of her baby, and for her health care providers, so they may choose the times at which to perform various screening tests and assessments,such as serum screening, assessment of maturity, and induction of labor for postdate pregnancies.
The 3 basic methods used to help estimate gestational age (GA) are menstrual history, clinical examination, and ultrasonography.
I think, I hope, it’s safe to assume that most of us find a 35-year gap extreme.
The date of feeling the first fetal movements (quickening) is far too unreliable to be useful.
Gestational age, or the age of the baby, is calculated from the first day of the mother’s last menstrual period.
Since the exact date of conception is almost never known, the first day of the last menstrual period is used to measure how old the baby is.
But let's be fair: There's a reason we tend to date people who are closer in age.
So, if something seems too good to be true (read: he or she is too hot for you by about eight years), it probably is.
