Has anyone ever felt like their heart starts beating a little faster or that you feel it beat harder?? And that your blood pressure drops low or your sugar levels drop so you get this empty nausea feeling? Not like your hungry but Thalia empty feeling where you just feel so icky? Sorry I really don't know how to explain that feeling but I don't know what it is and I've asked my OB all she tells me is to sit down wherever I'm at elevate my legs and drink something I have but I still get the feeling even after laying down for a couple minutes. Anyone have any clue as to what it could be it why and how they deal with it?
