Review of this test?

I took this test this morning with fmu. And this is what I got.

I went to my mothers office (she’s a receptionist at a doctors office). She got me to take one of the tests they had there, a urine test. No sign of a line.

How could I get the start of something on a cheap amazon test, but not one at the doctors office? Has anyone got a false positive with these tests?

I’m going to test tomorrow and the next day too. My period technically isn’t due until the 18th but I think I ovulated a few days earlier that expected.

God I hope I’m pregnant and it sticks 🤞🏻🤞🏻🤞🏻
