TTC and BBT chart all over the place

[Seltzerae]

Hello,

I have been TTC for a while now and trying to use BBT charts to figure out when I ovulate. I have PCOS and so my cycles have not been consistent until recently, after making dietary and lifestyle changes. However, I still can’t figure out when I ovulate in order to time things correctly. I take my temp with a BBT thermometer orally, at the same time every morning. I don’t get up, move around, talk, or drink anything before taking my temp. I don’t drink and sleep pretty well throughout the night. I’m not sure what to make of my charts. I just had my thyroid checked as someone pointed out my temps are pretty low. Should have the results in about a week. Can anyone tell me if my chart looks like I’ve ovulated? This chart is typical each cycle I’ve temped.
