Ovulation Issues...

I have PCOS so I'm not very regular. But my medicine has been helping that a lot. However. AF came 11 days earlier than last month. According to Glow, I shoulda ovulated last week but I felt like I just ovulated 2 days go. If I did, then I ovulated the same time as last month but just had an early cycle. I don't really understand. But is it possible to ovulate later than expected??
