The absence of a pregnancy test at 12 days after ovulation can only mean that the chances of pregnancy are small, it does not mean that there is no pregnancy.
For women with a stable menstrual cycle, intercourse during ovulation can increase the chances of conception. 12 days after ovulation without a pregnancy test, this means that the woman is less likely to get pregnant, but it is not hopeless, and can be postponed for a week to check again.
For women with less regular periods, not detecting pregnancy after 12 days of ovulation does not mean that the woman is not pregnant, it may be due to the shorter duration of pregnancy, the body’s human chorionic gonadotropin level is lower, so the detection of pregnancy is not possible.
Women are advised to relax and wait for some time before going to the hospital for a checkup so as to know whether they are pregnant or not.
