Pregnancy in a dream for a woman is an increase in her wealth. For a man, it is worry, grief, and sadness. A woman's pregnancy indicates that she persists in her affair and gains wealth and high status from it.

Pregnancy indicates blessing and wealth. For a man, it is a hidden worry. An old woman's pregnancy indicates strife. A virgin's pregnancy indicates trouble reaching her family because of her.

Pregnancy is interpreted as wealth. Whoever sees his wife is pregnant hopes for good from his world.
