NEED HELP

B

Hi beautiful ladies!

So I just maybe wanted some help on this as I may just be overthinking! So I tested yesterday (8/4 - 15DPO) and got the first 2 top pictures and then I tested again this morning (8/5- 16DPO)and got the bottom pictures. The lines on the first response test on the bottom is more fainter today than the one on the top. Should I be worried that it’s not as dark?

Thanks again ladies, just need to ease my mind 😌
