This is a faulty test, and the manufacturer leaflet probably says if you only have the test line then it’s not valid. I’m sorry.😔
Looks like you didn't have it in your urine long enough, so unfortunately, it is invalud. But it also looks like, if you had enough urine to finish that, it would have been positive. Grab a digital test.
I guess its still negative dis a test yesterday and today :-/ maybe next month 🤞🤞
Faulty tests buy a different brand
