Ovulation

Okay, so I know this is going to sound really weird and y’all will probably wonder why I’m posting it in the endometriosis page. I have endometriosis and I’m not sure if that is why it’s affecting me. I can’t seem to tell when I’m ovulating. I have a sex drive 99% of the time. Is there anything you can think that is different for you when you are ovulating? I can’t seem to figure out when I’m ovulating.
