Gave birth 11 days ago, thought I'd be able to leave the hospital at least with baby weight and amniotic fluid, but I only have -1kg, I don't understand why it is like this and the weight is still standing?, plus edema right on my legs and face. At one point it was -3kg, then again added 2kg. Is this not a pathology? I read that supposedly already on the 7th-10th day after childbirth should go away protein edema: ( here it's scary because it's still like this :( And what needs to be done so that the protein edema goes away?
