it is much more common to get a false negative than a positive, so long as you have not been taking HCG to help you conceive. i'd test again tomorrow morning with first morning urine, or wait a few days and test again.
also, i'm not sure if this is scientifically supported but i have heard that pink dye tests are more sensitive than the blue dye tests. you might want to try first response.
I have done a Clearblue digital test and it told me I was pregnant and conceived 3 weeks ago?? I did another 2 tests and they said Im not pregnant?? Am I pregnant? My friend said I am but probably very early??
First off dont waste your money testing twice in a day.HCG doubles every 48 hours.so if you had faint line this morning.test again in few days.if indeed your pregnant the test line will be darker.chances are your very early hence the fact line.6 days before is very early to test.anything can happen.Personally i would test day your period is due.
