Is this positive?

Nikki

I took this today , my AF is due today and got this i think v faint positive, this happened last month aswel and then I had a chemical, well I think it was because I got negative few days later but could it just be there tests either? Could they be a bit shitty? I'm waiting to go get a good brand one just looking for other people's opinions because I don't know what to think 🙈
