Late stages of prenatal development of human (i.e., fetus)

[LCCarmody]

Issue: Uberon's definition of 'late embryo' is "An embryo that is at the late embryonic stage; this stage covers late steps of the embryogenesis with a fully formed embryo still developing before birth or egg hatching. " and external definitions is: "Fetal structure, which is a developmental form of a vertebrate animal at any given time point from 8 weeks of gestation to birth (or hatching). Examples: There is only one fetus[FMA:63919]."

but, as per physicians, 'This is not the way the term "embryonal" is used in human medicine, e.g., https://www.medicinenet.com/embryo_vs_fetus_differences_week-by-week/article.htm'

Should there be a human (and other organism-specific?) term for fetus in Uberon? This issue is coming from this ticket. https://github.com/obophenotype/human-phenotype-ontology/issues/7362
