Should I test

Glow says I'm 7 days late...

Bled end of August/beginning of September, but wasnt my normal length, pain or heaviness...

Ovulated and had sex mid August.

3 vvvvvfl tests and multiple negatives up until about 2 weeks ago.

Spotted the TINIEST bit today.

Which I know, could be my period but could also be a sign of pregnancy.

Should I potentially waste my money on a test today?
