With my bfps at 9/10 dpo my lines start out like this and it does take 10-15 for the line to develop when this early with these tests. Congrats!

This happens to me when I test too early and it is pregnant. Test again in a few days and it should be darker! Lines like this one are how I figured out I had a chemical last cycle, but hopefully yours gets darker!
