Hey guys, so this sounds silly but I did a test because I’ve been unusually dizzy,

I did something extremely stupid and because I only had a tiny bit of pee I quickly dipped it in the loo, ( dumb I know I don’t need the harsh comments in that area 🤦🏼‍♀️) but as I did that I realised how dumb it was and chucked it straight in the bin, but I came back a half hour later and this appeared? Now I’ve heard of evap lines, I’m assuming this would be one of them?
