THe positive one!!! Congrats!!! If you get one positive test that means you're pregnant. The one that came out negative could have been with diluted urine
What brand did you use? Confirm Clearly is knows for its false positives, so don't get your hopes up yet if it is that brand.
Which test was positive (the first or second)? Your best choice is to buy an early pg test (i.e. First Response) and take it with your first morning urine
