The fetus won't remember at all. I wouldn't sweat over it.
A fall is not enough to cause any harm to the fetus. The fetus is inside a well insulated womb, capable of absorbing shocks. We have many pregnant women fall and their fetuses are fine while they have bruises.
She's not killing anyone or being a danger to society as a whole. Just being a pain, that's all.
