Faint positive line then disappears?

I took another test and I'm 11 days away from my period, I'm experiencing bad early pregnancy symptoms and today looked like I had implantation spotting?? Took a test and a positive faint line appeared then once it got to the negative line it disappears? Has this happened to anyone? It was first response so idk if i just tested too early. I hate the waiting game!
