I peed on a pregnancy test twice. Second time it showed positive?

I am curious to know if this is actually possible. I did a home pregnancy test as my period is quite late (I do have an irregular cycle sometimes) and the test showed negative. The next day out of curiosity I peed on the same test and it came up positive. Is this posible?
Thank you in advance.
