Could I got a false positive ???

Hey ladies!!!! Ok I use the digital clear blue to check for ovulation . I got a positive opk on cycle day 10 . No mucus no cramps or nothing . On dpo 8 I was having some really ache cramps and then about 2 hours after the cramps were over with I got a pink clear mucus discharge . What I think was ovulation not implantation because I’ve been getting BFN!!

And today I’m 16dpo and I got this so now I’m like so confused .

I don’t know if this is implantation or my period coming .
