dark lines?

Victoria

so I took this test at 5w4d at night when I found out I was pregnant. is there any reason why the lines are so dark? I'm hoping it means something good! I've have 2 miscarriages 4 years ago so I'm hoping this one goes well! I took another test the next morning and it was also just as dark. what do you ladies think it means? does that mean that it's a lot of hcg?
