What is happening !

Evie

So I’m late for my period. I have every symptom under the sun. But EVERY test has been negative. Every last one. Last night, I noticed brown blood and thought it could be implantation bleeding. This morning, I woke up with bright red blood. But super light flow. I wouldn’t said drops but I feel like I could go without a tampon and wear white jeans. That’s how light it is. I took a test and I don’t exactly know if it’s negative. Has anyone ever experience the line being the wrong way ? In the picture you’ll see that if it’s negative, that circle will stay empty. If positive, it’ll be a vertical line. But what if there’s a faint horizontal line ? What would that mean ? I sure hope y’all see that too.
