Pregnancy may not be detected until about a week after conception, and will be affected by the woman’s menstrual cycle and other aspects that cannot be generalized.
For women with more regular periods, intercourse around ovulation can increase the chance of pregnancy, then about a week or so after conception, through the early pregnancy or blood tests of human chorionic gonadotropin levels, so as to clarify whether the woman is pregnant.
It should be noted that if a woman’s menstruation is not particularly regular, and there are menstrual disorders, then the time of ovulation can not be fixed, and even if a woman is pregnant, there is no exact value for how many days after conception before pregnancy can be detected.
It is recommended that after unprotected sex, women can go to the hospital at intervals to check if they are pregnant.
