10dpo - do you see anything??

The first test is from this morning, and the second one this afternoon after holding as long as I could. Had tiniest bit of spotting in last 24 hours when I wipe, and lower back pain - obviously hoping it’s implantation but guessing by more likely AF.

I keep thinking I see something, but think it’s probably just indents. Tried to do the colour invert thing but hopeless at it. Think hearing from others that there’s nothing will help me let go of my chances this cycle 😊
