Almost 10 DPO

Liza • 👦🏻 5/5/16 👼 8/13/18 🌈 👶🏻 12/15/19 👧 12/4/2019 (our 🌈 baby came early) 🤰with baby number 3

I’m almost 10 DPO and tested today...BFN!! Af is expected in 5 days- should I wait to test again??? Also, experienced a creamy discharge for several days after ovulation- could that be a sign of implantation??
