Clearblue has always been on the cutting edge of pregnancy/conception tests.  They have come through with another groundbreaking test.  You will soon be able to find the exact day you conceived.  It will be meant to confirm your pregnancy as well as tell you the date of conception for about $20.  It will work like a regular pregnancy test, however, it will also contain two hCG hormone detectors.  A digital screen will tell you exactly how many weeks pregnant you are.  In labratory testing, it has proven to be 92% accurate.  Maybe Maury Povich can invest in some of these.  Perhaps when these become mainstream, he may be out of a job.
