Up & Up Pregnancy Digital Test (Target)

So today, 3 days before my cycle I decided to take a pregnancy test. I took the Target brand Up & Up and I guess I'm in a bit of denial. I took it twice and they both came back positive! What's the chances of false positive? If you've taken this test was it legit? Should I spend more money on another test? I plan on getting a blood test next week but I'd definitely like to be excited and tell my husband before then! =D
