But if it were only a week then it would still say 2-3 plus pregnancy tests don't test or read how much hcg is there, just that it's there. Even a digi is not entirely accurate. It's a guesstimate at best as it is only measuring your urine levels not blood which is by far more accurate and not prone to discrepencies based on how long you've held, how much liquids you've consumed etc. Don't give up hope!
