OPK but...

Rose • Mommy to Emma 🎀🌈 Wife 👩‍❤️‍💋‍👨 Educator 👩🏼‍🏫 Baby #2 due June 2021 👶🏻

So I am out of pregnancy tests. I'm also only 8 dpo so don't feel like wasting money on them right now...too early. I have a ton of OPK tests, and before I miscarried in Dec those showed positives. Is this dark enough to be a possible preggo positive? Or are these not at all reliable/hit or miss for pregnancy? And again, I know it's an ovulation test.
