We understand that when you are trying to get pregnant you might be excited enough and want to know that whether you can test your pregnancy as soon as possible. If you will go ahead and purchase a over the counter test kit to test the pregnancy just next day after your sexual intercourse then it will deliver long result. It is important to understand that the pregnancy tests are designed to detect the level of hCG hormones inside your body and it takes some time for your body to produce enough level of hCG hormone so that it can be detected by various test kits.
How Long After Unprotected Sex Can I Take A Pregnancy Test?
Theoretically as per research it is recommended that you need to wait for at least 14 days after fertilization of the egg. Although there are kits in the market which claim that they can detect pregnancy even 5 to 6 days prior to your upcoming periods but they will not produce hundred percent accurate result during that time however if you will use those kit on the first day of your missed period then that can produce 99% accurate result. If your menstrual cycle are regular then you can easily calculate your next period date and can accordingly go for performing any over the counter test.
So even though while these tests equipment or companies claim that they can produce accurate results even six days prior to your periods but it is always advised to wait for a day or two more even after the first day of your missed periods.
When the woman gets pregnant see starts to produce hCG hormone and for any test to be able to detect that hCG hormone it should be at the level of 5 mIU/ml and your body requires at least two weeks to reach that level. Now 14 is a theoretical number and depending upon an individual\'s body it might even increase.
What happens is that after the ovulation and conception the fertilized egg travels to the Fallopian tube to reach the uterus. Once it reaches the uterus it tries to implant itself against the uterine wall and this whole process starting from the ovulation till the implantation generally takes 14 days. It is only after the implantation your body produces sufficient amount of hCG hormone. Also it is not mandatory that you will conceive immediately after the sex you might even take 2 to 3 days more for conception and hence it becomes 14+3 = 17 days and this number is also different for different women.
For example Let's say if you and your friend are fertile on the same day and you also have sexual intercourse on the same day. You both go ahead and buy the same test kit and use it at the same day and same time, still there are chances that you might not get the same result as your friend. So if in case you do not receive an expected results than you can re test after couple of days.
