In my initial study in May I had 0 mins in stage N3 sleep which was disconcerting but understandable due to having undiagnosed (and misdiagnosed) OSA for probably 15 years. However in a titration study I did in early September, at which point I was compliant using APAP for 2+ months, I also had 0 mins in N3 sleep. I think this explains why I am still fatigued all throughout the day and have yawning fits in which I yawn a dozen times in a half hour at several points during the day. So I'm wondering, is there a way I can monitor my N3 sleep?

Not seeing how to edit my message now, but my pressure pre-titration was 6-12cm (determined by Kaiser), and the titration study in September was found to be 7cm. However during the titration study they started me at 5cm and increased it slowly & I slept very poorly (66% sleep efficiency with constant awakenings, 15 mins total in REM). By the time they got me up to 7cm the study was pretty much over. Since using 7-12cm in September, I've slowly increased it up to to 9-12cm now and am sleeping better than before, but as I said earlier nowhere near rested.
2 months is still early days for PAP therapy. Are your leaks under control? AHI? RERA index?
If your leaks are under control and AHI is under control and RERA is under control then O2 levels are not causing you to miss going into deep sleep.
If you are not Going to Deep sleep (N3/REM), then one potential cause is microarousals caused by pressure variations of the Auto PAP machine. These microarousals knock you out of a deeper sleep state to a shallower one, consequently not letting you get to N3/REM.
You may want to try straight pressure to rule this out. A good straight pressure to set is the 90% pressure reading of your machine for the last 30 days.
Started APAP 4-20, Closed range to 7.5-14, then straight 8.0 w/ Aflex 3
RDI always below 1. But sleep much much better at straight pressure.
Started on F10, Tried Quattro Air successfully. Finally settled on P10.
