Potential Ovulation - calling all experts!

Hi,

Please bear with me, as I don’t have many periods, so this is all rather new to me (/ digging up information I learnt and forgotten).

I have PCOS, so, I rarely have periods. I find it difficult to recall thoughts/feelings/sensations well as this is so few and far between for me.

I recently tested with opk’s due to a huge surge of EWCM and feeling headachy. I linked this feeling back to when I was Letrozole for two cycles in 2020. I use the Apple Watch overnight for a (loose) attempt at take wrist temps to decipher potential ovulation dips. I know this doesn’t work as well as bbt.

It would appear that I had my peak and it dropped off again over the past 2 days or so and my apps would be suggestive of O occurring yesterday (29th) however I had lots of cramps and sensations this morning until about lunchtime.

Would it be likely that today was O based on those sensations? I understand you need your days of bbt (ahem, wrist T) to confirm O temps. I am just wondering for my own learning and understanding.

Thank you!
