Dr. Carolina Arboleya answers this question in the following video:
It is true that these are very sensitive days on many levels because it is a bit like the end of assisted reproduction treatment. They are those days prior to the moment in which we will know if there is a pregnancy or not. The general recommendations are always to lead a healthy lifestyle. It is true that it is not necessary to rest on those days, far from it. You have to have a quiet, normal life. What does this imply? Well, logically on those days we are not going to run a marathon, we are not going to carry heavyweights, we are not going to make great efforts, but we can lead a normal life with complete peace of mind. Try to be accompanied by family and partner, have a good diet and try to control those nerves that it is normal and logical that they may appear.
