According to the search results, the chances of getting pregnant while ovulating depend on various factors such as age, health conditions, and timing of intercourse. However, the most fertile days are the three days leading up to and including ovulation. Having sex during this time gives the best chance of getting pregnant. The chances of getting pregnant on ovulation day are about 20%. If a woman has sex six or more days before she ovulates, the chance she will get pregnant is virtually zero. If she has sex five days before she ovulates, her probability of pregnancy is about 10 percent. It is important to note that these are general statistics and that individual chances of getting pregnant can vary depending on various factors such as age, health, and timing of intercourse.
