The chances of getting pregnant after 48 hours of ovulation are very low because the egg can only live in the woman’s body for 12-24 hours after ovulation, and the egg is no longer viable after 48 hours of sex, so the chances of getting pregnant are low. However, the only way to monitor ovulation is to have an ultrasound, which is the only way to see the eggs being released. If the test is based on the nature of the leukorrhea or using ovulation test strips, it is not very reliable and the chances of getting pregnant 48 hours after ovulation are not very good. If ovulation is confirmed by ultrasound, the chances of pregnancy after 48 hours are very low.
