如果你個期多數是很凖的而又遲了one week左右就不訪用捧捧去驗, otherwise如果你心急但又想有一個100% accurate result的話, you can go to your private doctor and ask them to do the blood test for you to check the HCG level. If you really bingo, the HCG will firstly reflect in your blood and then to your urine. The HCG can be found in your blood a few days after the conception but in your urine, it takes around 2 weeks.
