Condom leakage can lead to pregnancy, because if a condom leaks during intercourse, semen may enter the vagina, and if the woman is ovulating, the chances of pregnancy are higher; even if she is not ovulating, there may be additional ovulation, and there is also a chance of pregnancy. So if you find a side leak during the use of a condom, take the oral emergency contraceptive pill to take some measures to make up for it. There are many methods of contraception for women, but if you are a woman who has not planned to have children for a long time, you can consider intrauterine device for contraception, which is relatively simple and effective, avoiding the trouble of using condoms and worrying about condom leakage and other unexpected situations.
