PCOS & When to Take a Test?!

Rylee🧚‍♀️🌸🍄🌙

I have pcos, I know I ovulated but not exactly when. When should I test? The longest cycle I’ve had in the past was 45 days and I’m on cd43 today. I only have two digital clear blues and one FRER test on hand right now. I don’t want to waste them, but at the same time idk when my period will exactly get here. It’s already considered late, but not unusual, since I’m so irregular. TIA 💜
