The older the fetus gest the less effect teratogens has, some acceptations to this rule, most relate to disease processes. We know that malaria has a much higher incidence of fetal loss later in pregnancy because parasites have to cross from mother to baby blood stream. Greater surface area in placenta, the more likely malaria transfer can occur. Toxoplasmosis most common in torch, infects most cats and the cysts may be present in litter box, do not eat rare meats. Torch diseases category of various diseases that can affect development. Death of a partner/another child, impending divorce, spousal abuse (more commonly starts during first pregnancy, more severe during pregnancy, does not get better) Reduces blood flow to placenta, that can lead to underweight baby or stillbirth.
