If you have intercourse on the last day of ovulation, there is a 40-50% chance of pregnancy, because after the follicle ruptures during ovulation, the follicle survives for 24-48 hours. At this time the follicle is active and the chances of getting pregnant during intercourse are also high. If you want to prepare for pregnancy, you can buy a pregnancy test 12 days after intercourse to rule out the chances of conception. However, if you want to prevent pregnancy, it is recommended that you take emergency contraceptive pills to prevent pregnancy. A second abortion or medication can also have an unwanted effect on the uterus and the lining of the uterus. In the future, if you do not plan to have children, you should use condoms to prevent pregnancy.
