I think the idea of stress delaying is a load of bull. Who in their right minds has no stress? Those women who aren't "trying" and conceive are probably stressing over something else. Just relax when you can and try not to obsess...stress is unavoidable...if it isn't from TTC it is from your job, your family, your pet, your OH, whatever.
I love you all and I give you all the dust I can find (I scraped the bottom of the barrel)
