When should be try next?

Ok so we are going into month 8 of trying each month. Next time will be with our newest donor. We tried this last time with him but I think we missed out window of Insemination. I have read everywhere to try days before ovulation. Watched so many videos about doing it the day you get your peak on your ovulation test.

Our donor is willing to donate a few times SO should be try a couple of days before, day of surge and after? I need all the best advice for this next try please & thank you!!! 🤞🏻✨🤰🏼🌈
