Possible vfl? When should i retest?

I took this test in the afternoon at 12pm. Pic was 4 minutes after. My <a href="https://play.google.com/store/apps/details?id=com.glow.android">glow app</a> says I’m 1 week late for AF but my other app says I’m just 1 day late 🙄. My periods tend to differ a few days early or late every month but I’ve noticed my boobs are huge and full-feeling.

When should i retest?
