Please find a doctor who will check your ferritin levels. Although my hemoglobin and hematocrit levels were on the low end of the norm, a NEUROLOGIST finally checked my ferritin levels after having had a sleep study done which diagnosed restless leg syndrome! My levels were extremely low. At a 5 when they should be between 50 and 200. Concerning? A little for me, but more for you because you are pregnant. Chances are yours won't be that low especially if you eat beef, which I haven't for years. Anyway, I pray you discover the cause of your RLS. It is so frustrating not being able to sleep. I have found non-aerobic exercise like yoga, pilates,or squats helps some. Also if I go to bed BEFORE I am really tired, (hard to do with little ones) and read for awhile or listen to music. It seems the more tired I am, the more restless my legs become. A hot bath with a relaxing cup of chamomile tea and candlelight only has helped.
