Hello everyone, at 30 weeks I often feel like my legs are dragging and my head feels dizzy. I saw a neurologist, but they didn't prescribe anything, just told me to rest more. Have you experienced this condition? What did you do to cope with it? My blood tests are normal, but my blood pressure is below 110. And not higher.
