Pregnancy can be detected by a pregnancy test about 10-15 days after intercourse. However, the test paper is also subject to chance and may give a false positive or false negative due to many factors. Therefore, to determine whether you are pregnant or not, you can go to a regular hospital to have a blood test to determine the changes in HCG and progesterone. If there is a significant doubling and increase in both HCG and progesterone, you are pregnant. If both HCG and progesterone values are low, it means that you are not pregnant. For faster and successful pregnancy preparation, it is recommended to have intercourse during a woman’s ovulation phase, with both spouses relaxed and in good physical condition to avoid excessive stress and anxiety. Since pregnancy is a complicated process, it is also important to pay attention to rest after intercourse, avoid staying up late too often and develop a good work and rest schedule to welcome the baby in the best condition.
