Temping.... rant :(

I give up! I know I haven't ovulated yet and don't know if I even will. I have PCOS and just started metformin 2 weeks ago. Was told for women with PCOS Opks AND even cervical mucus aren't good indicators to see if I ovulate. That temping is the way to go. However, I work night shift....and depending what errands and things I have to do the following day, I don't always sleep at the same time. I also pee like every 3 or 4 hours, so I never stay asleep for very long. So temping is out as well.... so I give up trying to track my body...
