    …cutoffs for what constitutes early fetal loss, very early fetal loss, and so on. So actual estimates of how much these factors influence fetal loss varies. The safest overall estimate for any given pregnancy is probably about 30%, though one study, even with conservative estimates of pregnancy and fetal loss puts it at 60% (Holman and Wood, 2001).
