Positive strip test?

This was at 5 minutes. Could this test be faulty? I think I’m 14 DPO and would expect it to be darker by now. I’m 1 day late for AF. What’s the latest you have gotten a BFP? Also, did any look this light? All other pregnancies I was 10 DPO with a strip looking like this! Going to test with FRER at some point in the next 24 hours.
