The shared facilities for the Toei Shinjuku subway line and the KeiÅ New Line consist of two platforms stretching east-west five floors beneath the KÅshÅ« KaidÅ avenue to the southwest of the JR section. The concourse is managed by Keio Corporation but is in a separate location to the main Keio platforms.
Right now, the most sensitive pregnancy test on the market is the First Response Digital Pregnancy Test. It can detect the hCG levels in your body as many as six days early. Studies confirm that this test can detect hCG levels when they are as low as 6.5 mIU/ml.
It takes at least 2-3 days after implantation for there to be enough HCG in your system to be detected by the most sensitive test available, First Response Early Result. If you do test and it's negative, don't fret, just wait a couple more days and test again with the First Response Early Result. Good luck!
