I did a big no no!

Dyer waiting for 5 minutes and nothing showed up on the pg test I took it apar to see what it look like on the inside. But I looked at the strip and it ha what looked like the beginning of a second line. It's just right on the edges of te strip where the test line is suppose to be. Has anyone ever had something like this at te beginning of pregnancy? I'm two days late. And my period is like clockwork. ​
