So frustrated

I took a hpt and got a VFL. I leave to get dinner and come home and the line was faint but clearly visible. Of course I get excited. My sister in law then informs me that it isn't accurate cause it was read after 5 minutes. Accuracy to this? I was always told that if the lines are pink it's a solid if it's an off color it's an evap.. 😞 feeling so discouraged! It's like they think I am just making everything up. I feel like I have to prove myself.. here's the test..😑
