Yes. The reason you have to wait however long to take a test is because your body's HCG(pregnancy hormone that the test detects) level slowly rises, it dorsnt shoot up overnight. If you are experiencing implantation bleeding, you have gotten pregnant in the past few days so your HCG will not be high enough for a test to detect.
A bleeding time is the amount of time it takes for bleeding to stop in a bleeding time test, a test used to assess the ability of a person's blood to clot.

It is possible to have inconclusive test results, but not to test both positive and negative at the same time.
There are several things that can contribute to a negative pregnancy test even if you are pregnant. Some medications can give you a false negative, the timing of the test can affect the results. If you did not follow directions properly; if you let the test sit for too long the results may read negative after a while. It is important to read the results within the amount of time given on the instructions of that particular pregnancy test you bought. If you did not perform the test properly (example: you drank a lot of fluids before taking the test, which can dilute your urine). Etc.
Bleeding time is a crude test of hemostasis (the arrest or stopping of bleeding). It indicates how well platelets interact with blood vessel walls to form blood clots.
I miss my period 3 weeks now, i start bleeding, and pregnancy test came up negative.. i am so confuse because this is my first time
yes because if your bleeding your more or likely not pregnant!! but not all the time!!
Do it after seven days , as you might have ben to early the first time and it showed negative.
If it's a pregnancy test the answer is no, A test can come back negative even though its positive. But if it's positive, it's positive 99% of the time.
