There are various thoughts on the subject, women who believed that they fell pg because they lay in bed for two weeks and 'allowed' their embryo to implant, and yet others who think you should go about your daily life.

I have tried both, and I now actually firmly believe that you should go about your usual routine. In fact it is believed that the increased blood flow from exercising is helpful tp implantation, so both schools of thought have their pros and cons.
