Faint lines confusion!!

Di

I have done testing in 5 days and day 7 after transfer. I am confused ๐Ÿ˜. Pic 1 tested on day 5 after transfer

Pic 2 -Day 7 after transfer

I am sacred and canโ€™t stop my running thought. All I want that my baby stick to me ๐Ÿ‘ถ.

Day 7 was suppose to be darker if itโ€™s a good news but looks it it became faint. I still have cramps mild and worried.
