Can you tell when you ovulate??

Ca
Hi! Just wondering if any of you ladies can tell when you ovulate? I was diagnosed with pcos when I was 14. Now 25 and ttc number 1 with hubby for 18 months. I'm now on my first cycle of femara (cd 5-9), trigger shot (set at cd 14) and progesterone. I had the shot last week, and I know you're supposed to ovulate within 2 days, but don't know if I did as I don't ovulate on my own and didn't have any obvious symptoms after the injection. Can anyone relate?? I know you can do a blood test for progesterone to tell afterward, but I think the pills would mess that up for me?? Any thoughts or experiences welcome! Thank you!
