New To BBT Tracking

Amber

So I was supposed to start tracking the day after my period, but weather delayed my package from Amazon and I've only been able to track for a week this cycle, meaning my chart is very short on information, but is this normal? My tests were super dark yesterday (darker then the control line) and this morning I have ovulation cramping which I always get when I ovulate, but fertility friend said it can no longer detect ovulation, and glow and the premom app both moved ovulation day?

Is it just off because of lack of information, or am I doing something wrong?

Also for clarification, I take my temp at 6:20am vaginally.
