Had a blood and pregnancy test done but where both negative would it have been to early periods are due in 5 days

Pregnancy tests: Positive pregnancy tests only occur after implantation of the fertilized egg, and after the pregnancy hormone is greater than the tests lower limit. So it is best to wait until after the missed period, and if you want to know unequivocally, wait until one week after the missed period. At this time, the test will be either positive or negative, no in between. DrG
