Common Physical Changes During Pregnancy

Leg cramps. You may experience sudden leg cramps, feel that something is crawling on your legs or have an uncontrollable urge to move your legs, particularly at night. This symptom may be caused by low iron or potassium. Stretching your legs before bed and getting regular exercise can help; you might also try adding a potassium-rich banana to your diet. Ask your health care professional to test your iron levels; if they are too low, you may need a higher iron supplement.
