My tests seemed to take ages to get dark. Looked very similar to yours actually. Tests pick up different levels of hcg for everyone. My mum got a dye stealer at 4 weeks and I still hadn’t got one by 8 weeks and have taken tests since and still no dye stealer. My tests took 3 days to look significantly darker. I’m 20 weeks and everything was perfect for both me and my mum. Try not to worry. As long as they are positive and not getting lots lighter. These tests look good to me x
