Charting Inquires

This is my first "real" month charting I tried last month but I was on vacation so there was alot of missing days. Just curious to see what others think, is there anything I should be concerned about, something particular I should probably focus more on or does everything look okay so far. I'm currently 7 DPO, one app says ovulation was the 7/4 but another app says 7/7 based off bbt. I did not have the EWCM and its VERY rare I have any ovulation symptoms.
