So I have had my iphone x for a year and my apple watch series 4 for four months. Yesterday I noticed that my activity history before May 17th is gone. I have been using the watch since February 12th, but anything before May 17th only shows my total calorie burn and any awards I had received. Has anyone run into this or know how to fix it? I have done all the basic troubleshoot, unpair and repair, reset my settings but nothing seems to work.

If you restored the phone from an iCloud backup your watch data would also be restored. If you restored from an iTunes backup that data would be there only if you were encrypting those phone backups. If you weren't then the data is gone.
When you unpaired the watch a backup to your phone would have been created and then had you done an iCloud or encrypted backup to iTunes that data would have been preserved in a subsequent restore. Then when you re-paired the watch to the new phone you, I believe, would have been given the option to restore from that original unpaired backup.
