What happens after negative FET?

Could you please elaborate on what typically occurs following a negative FET? I'm curious to know what steps are typically taken by patients and doctors alike in such scenarios. Do they immediately proceed to other fertility treatments, or is there a recommended period of rest and recuperation? Also, are there any specific lifestyle changes or dietary adjustments that are often recommended to improve the chances of success in future attempts? I'm interested in understanding the entire process and the various factors that could potentially influence the outcome.
