Preparing for FET

Hi! Would love any advice on how to prepare for the transfer. I’m having my egg retrieval next week but I’m wondering what restrictions you had after retrieval. My grandfather is really sick so I’m thinking about taking a flight before the transfer since I’m prob not transferring for another month. Not sure if it’s ok to travel though. My nurse said the transfer is more flexible/less restrictive than the retrieval but I don’t want to mess up anything for the transfer. Any helpful advice for the time in between I would love to hear!
