so scared! what does this mean?!

this is my first pregnancy - i’m 5w5d and have never gotten that blazing dark positive that i see so many people get. the last three tests were taken three days between each (12/20 - 12/23 - 12/26). today it’s practically negative 😭 what does this mean?! did i miscarry? i really haven’t had any symptoms just boobs a little sore. but haven’t had any spotting, bleeding, or cramping or anything that i think would be a sign of miscarriage. i feel like it’s way to early for hook effect to be a possibility, but also don’t know much about when that would happen.
