The last couple of days ago I noticed I wasn't urinating very much could this be because of the calcium? I stopped taking it yesterday and drinking a lot of water. ankles swollen a little, not much. I'm 71 years old and very nervous about this. My Dr wont be in till Monday, is it ok to just drink a lot of water and wait till Monday to call? She increased the calcium because I'm getting osteopenia thanks Marti
