I honestly wouldn’t worry about that test being lighter. I did exactly the same, got gorgeous lines on cb and frers. Tested a few days later with a different brand it wasn’t as dark as I expected and I stressed myself out. Went out and bought a box of frers and had lovely dark lines and with more progression x
I’d go get a box of frers and stop testing afterwards because we just stress ourselves out all the time over tests lol best of luck Hun, I’m sure your fine xxx
