Try a different brand, first response stopped selling to the uk years ago so most/all the first response you get from Amazon are fakes and not very reliable x
@Hollie Thank so much for commenting 🫶
@Mia I had no idea about that 😮 I’ll try with a different test tomorrow. I wonder why they stopped selling to the UK! I bought these from Amazon too!
Don’t use these tests to look at proper line progression. They’re all different.
They definitely darken as they dry and maybe your urine was more diluted? Try not to worry, do another one on OTD 🙏🏻
