kind of an important emotional question as some couples have been trying to get pregnant for years
And for some just the opposite... like 19 year old me decades ago -- ambiguous test result, and no 24 hour drugstores at the time so led to a sleepless night for both of us until we could get a second test the next day. It was negative. Would have much rather had an unambiguous POS/NEG result.
If it was ambiguous, these digital tests may have told you it was negative even when it would be positive a day or two later. You might have slept better but it wouldn’t have been based on accurate data.
The second test had more clear instructions about "read results after X minutes, ignore any changes after that time". The electronic test wouldn't have had a visible line after 10 minutes that scares young college students when they think they can see the shadow of a second line if they hold it to the light the right way.
