Getting pregnant is not an easy task, but understanding the essential physiology of the process is the best place to start. In this chapter I will describe the arduous journey that sperm must make through the female genitals to reach the egg, as well as the simultaneous adventure of the egg during which it matures to become genetically ready for fertilization, erupts from the ovary, and gets grabbed by the fallopian tube, fertilized, and then hustled along into the womb at exactly the right moment to implant. Failure of the sperm or egg to make an important connection anywhere along this complicated itinerary will prevent pregnancy from occurring. The vagina is an elastic canal, about four to five inches long. At the end of this canal, in the deepest recess of the vagina, is a structure called the cervix, which is the entrance to the womb, or uterus. The uterus is a hard, muscular, pear-shaped structure with a narrow, triangular cavity inside, so small that it would barely hold a teaspoonful of fluid.

You know that sex leads to pregnancy , but how soon after sex do you actually get pregnant? Implantation occurs five to 10 days after fertilization, which means anywhere from five to 15 days after you had sex. Pregnancy symptoms may start as early as a week after you had sex or may take several weeks to start. Some women never get noticeable early pregnancy symptoms. So, fertilization can occur within minutes of sex

When trying to become pregnant, many couples plan intercourse between days 11 to 14 of the woman's day cycle. This is when ovulation occurs. However, it is hard to know exactly when ovulation will happen. Health care providers recommend that couples who are trying to have a baby have sex between days 7 and 20 of a woman's menstrual cycle.
