No, it really shouldn’t. If you have a glaring positive on a digital pregnancy test, then the chances that you’re not actually pregnant are slim to none.
However, if you’ve taken just regular, plain ol’ pink or blue dye test and they’ve come up negative while a digital is saying “positive” that’s a little suspicious. Likewise, if you have other digitals coming up “negative” but a random “positive” on another digital, then it’s possible that there’s either a glitch on the supposedly positive test. Or, the more likely scenario is that you’re really early on and getting varied results because the pregnancy hormones haven’t properly built up in your body yet.
Give it two more days and try again with another digital to confirm.
If the digital is positive and you have a bunch of other positive tests too, then wake up, you’re pregnant!
