If you want to test whether you are pregnant, generally speaking, you need to wait for fertilization to be successful before taking the test. However, sometimes a negative test result may occur even within a few days of successful fertilization. Therefore, if you want to test whether you are pregnant, it is best to wait until you see a positive test result.

Before taking the test, you need to make sure you have practiced safe sex and not used any unsafe testing methods. Additionally, if you have any medical conditions or are taking medications, test results may vary.

If the test result is negative, it is recommended to wait for a while again until you see a positive test result. If you're still unsure whether you're pregnant or have any other questions, talk to your doctor.

A good way to test for pregnancy is to test on day 14 of your menstrual cycle. Also, ensure that safe sex practices are practiced and that no unsafe testing methods are used. If the test result is negative, wait a while again until you see a positive test result. If you're still unsure whether you're pregnant, talk to your doctor.
