Why Does It Take That Long After Pregnancy To Start Vomiting?

Pregnancy is very long and takes approximately 39 weeks to complete. If the baby is born within thirty-seven weeks of pregnancy, then it is called preterm. If the delivery takes place between thirty-seven to thirty-nine weeks, then it is called an early termination. If the child is born between thirty-nine to forty-one weeks of pregnancy, it is referred to as the full term. In contrast, late-term is used when the baby is born after forty-one weeks of pregnancy. In present times, delivery is mainly carried out by an operation.

Symptoms such as vomiting result from the increase in the pregnancy hormone, scientifically termed as HCG that is the Human Chorionic Gonadotropin. As soon as the sperm enters a women’s vagina and goes for mating the female egg, the body starts pregnancy hormone formation. Although the process is prolonged initially, it gradually increases as the sperm fuses with the female egg. When the hormone level reaches a certain level, the woman starts vomiting and experiences mood swings frequently.

In most cases, vomiting will stop automatically at the end of the fourteenth or the fifteenth week. Even after that, the mother is facing vomit issues; then she should consult a medical practitioner as soon as possible as any delay could cause health issues to both the mother and the child.
