A true knot in the umbilical cord is exactly what it sounds like: a knot that forms in the baby's umbilical cord. It normally form between nine and twelve weeks of gestation because that is the period when the amniotic fluid level is very high. There is also evidence that true knots form during labor.

Is it fatal for the fetus if the knots appear so early in pregnancy?
When the true knot remains tight, it may impede the circulation of the fetus and may result to fetal death in utero especially in labor.But it i extremely rare.
