If anyone has a Fitbit, then you know my chart is crazy. But I can't get enough sleep while pregnant as it is. Much less when I'm this restless. I don't know what to do, I'm at my wits end. I'm so tired all of the time and no matter how much sleep I get, it's never good enough. I know sleep is so important for a growing baby, but even when I sleep for 12 hours I only get 2-3 hours of good sleep. I know this is accurate as well, my boyfriend has a Fitbit and only has 1-3 light blue restless lines for the night. He said I toss and turn like he's never seen before. I don't know what to do!! Help!!
