2 weeks have passed since expected AF but BFN 1 week ago. Going to retake this afternoon 🙏🏻

Hi Everyone, so been TTC for over 2 years. So far no luck. This cycle has been strange. Usually my cycles are regular 31 days long, but I am 2 weeks late, no AF and no BFP... I took a test day after expected period and 1 week after also... and no BFP but today I’m going to retake after work as now 2 weeks late... has anyone ever had a BFP so late after missing AF or experienced a late AF and know what could be causing it.... ?!?
