How do I prepare for ovulation?

I just did a series of tests to confirm my body in general was healthy. Thyroid, liver, everything and everything was perfect. I’ve been having irregular periods recently due to stress but last night I finally got it after 28 days and I’m not anxious anymore. I’m on CD2 but I got my period late last night so it could be CD1. Without medication like Clomid which I was desperate for (even though I’ve never had a reason to take it I just was not getting pregnant) how do I prepare for ovulation? How can I make as sure as possible that I am am/ could ovulate this month? What helps please anyone? I’ve been trying for so long and I hate being told “just wait”.
