OPK test stick

[Stephaniem05]

I would like some advice please . So last month around the 20th and 21st I had OPK kits that were positive . I am due for my period on the 9th of Feb . I took an OPK test today ( I know might seem a waste I just wanted to see what it said ). It’s came back very light but I would say it’s positive . Is that not quite weird or odd. Maybe is just my cheap OPK stick ? Any ideas ?

If it’s light then it’s not positive, has to be same colour or darker than test line to be positive
