When do I even ovulate this month?

I got my period October 9th and it lasted until the 13th. I started bleeding again on the 21st and that lasted until the 22nd, I went to the doctor and got diagnosed with Polymenorrhea; I thought the bleeding may have been implantation or breakthrough bleeding but no. So, now... I have no idea when I'm ovulating or not. So if I even get pregnant, I won't even know when I conceived 💀💀💀💀
