Planets surrounding the ascendant and twelfth-house signs reaching the ascendant describe the situation leading to our birth and the birth itself:
Aries or Mars - A pregnancy with some conflict, arguing or emergencies is common with this placement. Either the mother or father may fight to terminate the pregnancy or keep the child. Difficulties with the birth are common. Surgery during the birth or after the birth on either the mother or child are common. The prenatal experience is stressful for the child and this placement is often found with premature births.
Taurus, Libra or Venus - A pleasant pregnancy where the mother is calm and relaxed is natural for this placement. The mother may indulge in excessive amounts of food and treat herself to relaxing activities and music. They may be issues regarding money and expenses along with an evaluation about a possible change in values for the family either during the pregnancy or when the child arrives. The prenatal experience is relaxing with the child and the birth may occur late or be induced because the mother does not go into labor on time.
