I think pregnancy can be detected as early as 21 days after conception through a test such as ClearBlue, that's whether you are on a period or not.
upto 5 days before your due period, you have more chance with an internet cheapie test to detect really early as they start from detecting 10mul of hCG.

No. Fertility tests are made to detect FSH not hCG. You will need to buy an actual home pregnancy test or see your Dr.
Not at all.
It all depends on how much of the pregnancy hormone (HcG) the pregnancy test can detect. Some detect as low as 10 mg of the hormone, and some take up to 100 mg.
human chorionic gonadotropin or hCG
the most sensitive test on the first and second day after a missed period was First Response Early Result. It appeared to detect pregnancy in 95 percent of women. The second most sensitive test was Clearblue Easy. In a follow up study it appeared to detect 80 percent of pregnancies.
There are a lot of things that can prevent the HCG level. It could be the intake of fluid, or it could be that your body has not produced enough HCG to detect a pregnancy.
Yes, if it's too early you can get a false negative (ie. there isn't enough HcG in your urine yet for the test to detect). It can tell you you're not pregnant when you actually are in the very early stages. If you miss your period, take another test.
A pregnancy test, either blood or urine detects the hormone hCG.
