If you don’t ejaculate during intercourse, but there will be a certain amount of sperm in the prostate fluid, you may also get pregnant.
Just because you don’t ejaculate doesn’t mean that no sperm enters the woman’s body. During sexual intercourse, the man produces prostate fluid when he is aroused, and there will be a certain number of sperm in the prostate fluid.
If you are ovulating, it is still possible for these sperm to pass through the cervix and reach the uterine cavity. This is especially true for women with irregular periods who are unable to accurately predict ovulation and can still get pregnant if they don’t use contraception during intercourse.
Therefore, if you do not intend to get pregnant, it is best to use contraceptive measures during intercourse, such as condoms, to avoid accidental pregnancy, and ejaculation is not a guarantee of contraceptive success. If there is a delay in menstruation, it is recommended that you seek medical attention.
