Confused, indent of VVFL

Today is 9dpo and craved and tested early was expecting nothing but I see something. I’m fairly new to the whole testing etc but have read FR is known for indent lines. Is this a nasty indent or the start of something. Did invert it and there is a lighter colour line but tbh don’t know if indent lines glow or not 🤷🏼‍♀️🤦🏼‍♀️ did use the other test in the pack with warm water and it didn’t have indent this visible and they are from the same pack 🤷🏼‍♀️
