The question how soon after sex can i take a pregnancy test can be answered by first gaining knowledge about how a pregnancy test works. There are two types of pregnancy tests and both of them work in the same way. There are blood tests and urine tests. Both of these tests however work in the same way and this is by detecting the presence of the hormone HCG. This is an acronym of Human Chorionic Gonadotropin. This is the hormone that is responsible for all the changes that occur inside the body once pregnancy occurs. This is after the process of implantation. The HCG doubles in levels after every 48 to 72 hours and it is usually best to wait for a while before taking the test. This is so that the hormone can be easily detected by the test.
A woman also needs to understand how her cycle works so that she can know how soon after sex she can take a pregnancy test and get the correct results. The first day of a womans cycle is the day that she gets her first period. The woman ovulates 14 days after she starts her period and this is usually the most fertile time of a womans cycle. This is the time that a woman is bound to get pregnant especially if she has sex a few days to or on the day of ovulation. When the egg gets fertilized, it travels down to the uterus where it implants itself on the wall of the uterus. It is at this time that the HCG hormone is produced and any time after this is okay to take a pregnancy test. This is usually 7 to 10 days after ovulation.
If you are having a blood pregnancy test, you can take the test 7 days after ovulation. At this time, implantation has taken place and the HCG has been produced. The HCG is however in low levels and the blood test is the one that is most appropriate to detect the low levels of the HCG. 14 days after ovulation is the perfect answer to how soon after sex can i take a pregnancy test. This is because at this time, the levels of the hormone HCG have been detected and it is therefore to use a urine test and get the correct result. This is also a good time because the cycle is ending and the woman will miss her period which will prompt her to take a pregnancy test. She will be sure to get the correct result because she gave herself enough time for the pregnancy to settle in and become detectable.
