Try to relax into Savasana pose for 5 whole minutes
Certain studies have shown that stress significantly reduced the probability of conception each day during the fertile window.
Yoga just happens to be a fantastic way to relieve stress. It can be as strenuous as you want, but there are tons of easy poses, like savasana or "corpse pose." All you have to do it lie down on your back on the floor with your arms and legs slightly spread out. Then close your eyes, breathe, and relax!
