How long after sex can I take a pregnancy test?

The most important issue for couples who want to have children is how long it will take to test for pregnancy after having sex. Many women want to use pregnancy test sticks to detect whether they are pregnant. At this time, they need to first understand the answer to the question of how long after having sex to test for pregnancy, so that they can have a rough idea.

How long after sex can I test for pregnancy?

Generally, a test strip can be used 15 days after the couple has sex, and a blood test for HCG can be done a week later to confirm whether the pregnancy is confirmed.

The ovulation period is around the 14th day of the menstrual cycle. If fertilization is successful at this time, it will take 6 or 7 days for the combination of sperm and egg to produce HCG, and the pregnancy test sticks are all determined by testing urine HCG. HCG actually starts to secrete in large quantities after the fertilized egg implants, and the transformed trophoblasts begin to secrete and produce HCG in large quantities. It takes at least 11 days for the fertilized egg and embryo to implant. Therefore, for the first 6 days, if you want to be more precise, wait until 11 days, then it will be more accurate.

Using a pregnancy test stick can simply and relatively accurately test whether a woman is pregnant, so it is very useful for female friends to know when to use the pregnancy test stick most accurately. However, pregnancy test sticks are not very accurate, so if you want to know for sure whether you are pregnant, it is better to go to the hospital for a check-up.

Also, don't drink too much water in an effort to increase your urine volume, as this will dilute your growth hormone levels.
