I personally like ovufriend better. But I used both of them this month anyways!
Your temp should be low before ovulation, then will increase post o when your progesterone increases.
I tried charting cervical position this month, for the first time, and I found it somewhat difficult. Maybe next month will be easier. But I'm still not sure what open and closed truly feels like.
Charting cm was helpful though! I found it a bit subjective at times, but it was nice to see when I had ewcm.
Good luck next month!
(I'm in the same boat as you, AF got me today. How long are your cycles?)
