Exercise after iui???

Ok ladies..i am 2dpo and am wondering on what ur thoughts on exercise is during this dreaded wait. I have read both things. Some say it's good to have circulation blood flowing etc and others say take it easy. My Drs office says it's ok just as long as its noting intense like crossfit or hot yoga. I won't do anything more than walk away the pounds these two weeks. What do u guys think?
