Recovering missing photos from October 2024 to March 2025 on iCloud and Google Photos

Months of my photos are gone.

I am missing most of October 2024 to March 2025 and just realizing it as I’m looking through my photos on iCloud & Google Photos.

I pay for a subscription for both, wondering if anyone has any recommendations for me to get my pictures & videos from that period back?
