Ovulation without a condom did not ejaculate inside, this situation also has the possibility of pregnancy. Even though women use ejaculation outside the body for contraception, no form of contraception is foolproof and does not achieve 100 percent contraception, and ejaculation outside the body is no exception. As long as a small amount of sperm travels into a woman’s pelvic cavity, there is a chance that she could become pregnant. So in this case, if a woman experiences delayed menstruation, it is recommended that she go to the hospital as soon as possible to check her blood HCG values to rule out pregnancy. If the blood HCG rises, it suggests that the patient is pregnant. In addition, if a woman does not want to have children, she should try to avoid coitus during the ovulation period, or use condoms or IUDs, or take oral contraceptives to prevent the possibility of pregnancy.
