HI, thanks for using healthcare magicPregnancy
tests detect the level of HCG
hormone which is released during pregnancy.
This hormone is normally detectable in the urine 11 to 14 days after conception. It is detected in the blood a few days before this.
You can consider performing the test at this time. If it is difficult to estimate this time period then you can consider doing it at least a week after a missed period.
I hope this helps
