Ovulation after Miscarriage - BBT help

Hey all, Im looking for some clarity. First about me - I’ve been diagnosed with PCOS since 13, I’m 29 now; naturally, by losing some weight, eating healthier and supplements, I regulated my cycles and have had “normal” cycles for over a year, they came on time, every month. Me and DH have been TTC for 2 years, 1 MC. I Found out on vacation in august that I was pregnant for the first time but I miscarried a week later in September 2024

Now the question - Since the MC I had a period in October (beginning of chart) and skipped November. I’ve been trying to track my bbt as BEST as I can, I’m very forgetful unfortunately and have a horrible sleep schedule so it’s hard to keep up with it at times. Currently I just finished my period for December (end of chart) which lasted 5 days-ish. My question is how do I understand my bbt chard for the past 2 months? I have a lot of peaks and dips but I’m not understanding if it shows that ovulated or not. Can anyone help me understand? I also added my chart from Premom as well for reference.
