Thanks for sharing that. I have done two IVF cycles, each at a different clinic and neither of them recommends bed rest. They recommend taking it easy (i.e., don't do hot yoga, etc) and no worries about getting back to normal right away.
I'm doing my 5dt tomorrow AM and have to travel first thing Friday morning to attend my grandma's funeral...I don't really have a choice about either one so I'm hoping that my day off tomorrow after the transfer is enough "taking it easy". I did bump my flight to first class on Friday morning though. :-)
