Oddly, iron deficiency wasn’t mentioned in the article.  Pregnancy can make you anemic because you’re increasing your blood volume by almost 50% in a short time. Anemia will make you tired and short of breath. Standard blood tests will show if you need iron supplements, but it can take a while to get back to normal levels, and exercising during that time will be difficult to impossible, depending on how anemic you are.  This may be why the fatigue hits so early in pregnancy – there are athletes who didn’t realize they were pregnant until they saw their performance declining.

Blood donation groups like the Red Cross advise against heavy exercise the same day you donate, to avoid reopening the needle wound and because you may feel dizzy or faint from low blood pressure.  Be aware that frozen blood has a 48-hour lifespan, compared to four weeks for fresh blood, makes me understand why there are constantly blood drives.  But the last time I checked, those on blood thinners are not allowed to donate.  If you can, please consider donating or encouraging those who can to donate blood.
