7DPO. (I know so early. I promised myself I wouldn’t and 🤷‍♀️)

I took this and I stared at it for a minute and it looked like I could kinda see something so I just set it aside not to drive myself crazy. But that was a lie because 30 minutes later I’m looking at it again and I see this. Picture doesn’t do it much justice as there’s a very clear blue strip in the front. Is this an evap or start of something?

I’m gonna wait a day or two and test again.
