I have never used preseed.

Im really hoping that is the case because i am very concerned. I know my last pregnancy i got 6 positive on a digital like 3-4days before my missed period. And then when i miscarried when we where at the ER they said my HCG levels where only at 12.....which they said was abnormally low....but they may have already dropped substantially that day.

also, if you aren't already using preseed, I highly recommend giving that a try!

@sharalachez, try a line test like FRER. digitals require higher levels of HCG. and since you can implant anywebre from 6-12DPO you could have implanted later. if that did happen, you'll need about 3 or so days for HCG to rise. you're not out until your period shows though so don't get discouraged!
