Confused with faint lines

Di

I have done testing in 5 days and day 7 after transfer. I am confused šŸ˜. Pic 1 tested on day 5 after transfer

Pic2 -Tested in day 7

So pic 2 is lighter than pic 1. I am sacred if this all looks ok. I can not control on my thoughts. Just want my baby stick to me šŸ‘¶
