Please help😭😭

Kaya
So I am 13 days late as of today. And I am usually never this late. I had protected sex in January around the 14th and I got my period in February on the 2nd and it ended the 8th. I took a pregnancy test but the test it self was expired by a month. Is it possible that I could be pregnant? And that the test is wrong? Or am I over reacting?Â
