Conclusion
The pregnancy test results depend on the sensitivity of the kit and how well the person followed instructions and interpreted the results. With the majority of the pregnancy kits now available, hCG detection in urine can be done within 3-4 days once the implantation is done, it often takes much longer. If test conducted early, it may not detect hCG because of low concentration. The hCG level in blood can rapidly rise after implantation and is at its peak within 7-10 weeks and starts declining thereafter.
When a woman is pregnant and she misses her period, around 75% of the tests can be positive while 25% of them can still be negative. As a result, you should not 100% rely on the first pregnancy test results. Continue retesting until you are 100% sure. In most of the cases, if the test result is still negative after you miss the period, the chances of pregnancy are very low. The positive result of a pregnancy test would show up after or even before you miss the period.
