Vvfl?

All I had was a blue dye, this was taken within time frame. I know it’s very faint but I saw it in person as did my friend. My period is due in 2 days and I tested again this morning and got a negative. I’m feeling really upset because I don’t know whether to think this was a vfl or a horrible indent or the start of a chemical pregnancy (early mc). Picture was taken around the 3-4 minute mark.
