Ovulation pregnancy probability chart

To show the probability of pregnancy during ovulation, we use the following chart:

| Time | Ovulation | Not pregnant | Pregnant |

| No. 1 | 10% | 90% | 10% |

| No. 2 | 20% | 80% | 20% |

| No. 3 | 30% | 70% | 30% |

| No. 5 | 50% | 50% | 50% |

The chart above shows a woman’s probability of becoming pregnant within 5 days of ovulation. It can be seen that the probability of pregnancy during ovulation is very high, almost 100%. However, this does not mean that pregnancy is inevitable during this period, as there are many other factors that affect a woman's probability of pregnancy, such as age, health, and menstrual cycle.

To sum up, it is very important to understand the probability of pregnancy during ovulation, which can help women better plan their reproductive process and take necessary measures to protect themselves and their fetuses during dangerous periods.
