In brief: No

This also known as the rhythm method, which is not a reliable form of birth control.
The best options for birth control are condoms, oral contraceptives, diaphragms, and intrauterine devices. Each one of these devices, has there own rate of protection. Which one you use depends upon your preference and medical history, as well as, if you smoke.

In brief: Ovulation

You can get pregnant around the time of ovulation--usually around day 14 of cycle.
Day 1 = 1st day of your period (bleeding). However, sperm can live in the uterus for up to a week so there is huge time frame for conception. Also, ovulation does not always happen around day 14. Using the cycle as a birth control method is not reliable. Condoms (protects against stds) or bc pills are more reliable.

They rythym method is notoriously unreliable. In addition to sperm viability, sex can also induce ovulation causing ovulation to occur early.

In brief: No

Conception depends upon ovulation, having sexual intercourse during 5 days before ovulation to 2 days after ovulation ( highest fertility period ), presence of both the female egg in the fallopian tube and the male sperm cell during the same period.
A women not getting pregnant without using any birth control methods is not a viable method. Chances of conceiving over a period of 8 months is 40%.
