Hello! I am a recently converted lurker as well.
I haven't even been here as long as you have but with regard to charting, as long as you're getting three hours of uninterrupted sleep at the end of which you can temp, I think you could try temping. I just started temping this month which is my 3rd cycle TTC. My periods are also very regular but I wanted to confirm that I was ovulating. As far as CM, I only make note of my EWCM, which for me only coincides with O, I don't get it any other time of the month.
FX that this is your month!
