I’m confused

I’m not even sure what’s going on last I tested it was 16dpo and the test was very faint. And then by the afternoon I got a period literally til today. Then I decided to test and it lit up?

I’m still waiting for my doctor to send me a requisition to get blood work.

but this is honestly killing me I don’t know if it’s a false a positive to be happy. Arghhh

Has this happened to anyone?
