The fertilization of sperm and ovum occurs at ampulla isthmic junction of fallopian tube. This ovum travels to the uterus and joins with the uterus for further development. Two weeks after the fertilization or conception, pregnancy is said to begin.
This is accompanied with missed periods or menstruation. Other important presumptive signs include nausea, vomiting, breast tiredness, back pain, poor sleep etc. In humans, the pregnancy or gestational period lasts for around 40 weeks or 80 days. Estrogen, progesterone and human chorionic gonadotropin are the three hormones that rise at the start of pregnancy.
Estrogen regulates progesterone and increases blood flow while progesterone prepares the uterus for implantation of fertilized ovum. The third hormones indicates the creation of placenta.
