Ovulation is an important period for pregnancy, and if you have sex during this period, your chances of getting pregnant are higher. However, not all sexual activity leads to pregnancy, and pregnancy is not always detected within 15 days.

However, even if the test card shows pregnancy at this time, it cannot determine whether you were pregnant on the day of sexual intercourse. This is because HCG takes time to reach the body, and it takes some time for the pregnancy to count. Therefore, if you want to determine whether you are pregnant on the day of intercourse, you need to wait until the number of days pregnant is increased before taking the test.

For couples who want to have a baby, the 15 days after sex may be a critical period to detect pregnancy. If you miss this opportunity, you may have to wait longer to test it out.
