In need of advice

According to this app I’m 5 Days late. I tested on the second day and the test came out to be negative. Was that too early? Also, the ovulation boxes in my clue app keep moving into February what does this mean? It says i started on28 and ended on the third but last month it said I started 24 ended on the 31. On the <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">Eve</a> app it’s saying it started 22 to the 28. Please help
