Vfl… need help

I took a pregnancy test last Wed and it was vfl… this is my test from today still vfl. It’s been a week since I found out and my line hasn’t gotten darker. I went to the er Sunday because I was bleeding from wed - Sunday bleeding like a light period but I was scared I was having a miscarriage again so I went in. Ultrasound showed nothing… either too early or had lost baby already levels were 48. And they told me to just get it retested in a few days… im just scared that something’s wrong since the line isn’t getting darker
