Should I test today?

I never got a positive opk so idk when I ovulated, but it's currently 9 days until my period is due! I have three .88 cent tests from Walmart, one digital hpt, and 3 FRERs. I'm dying to take a test because I'm dying for my BPF! Should I test today? Is it possible to get a positive? When should I test? Help! Never been so excited to POAS. 😭
