Electric heated mattress post FET?

[Roo45]

I've read it's good to keep uterus warm during FET so have been using a heated mattress at night but now reading that heat can affect embryos? I'm worried I've caused damage now?! My clinic didn't mention anything about heat just not too exercise too vigorously or heavy lifting, I am planning to ring them and check. X

I was told not to work from home with my laptop on my stomach after my FET due to the heat transference. I guess it depends on how hot it gets? Is it a noticeable heat? And do you sleep on your stomach?

I sleep on my back or side I'll usually switch it off before I actually fall asleep and don't put any direct heat on my stomach. I called my clinic and they said it shouldn't make a difference as my body should self regulate the temperature, think I just need to stop googling things lol literally every time I eat or do something I'll Google it to check if it's safe post transfer! It's been 9 months since my last FET and this is my first 3 day transfer and maybe that's upping my anxiety
