No period, not pregnant, know I ovulated


So. My period is due today, but hasn’t show up. I’m not pregnant (took a test today). I know I ovulated 14 days ago by tracking with OPKs. So what gives? Why hasn’t my period started? Stress? I thought that whenever my period was a few days late it generally tied to ovulating later than expected, but this time I tracked it. Should I expect it in the next 2-3 days I’m guessing? Like I know that stress can affect periods, I guess I’m just confused why it hasn’t started if I did ovulate two weeks ago.
