So every now n then I have felt almost like I've got a ball or hair ball or somethin in the back of my throat like midway down if that makes sense bit Tmi I have tried coughing it up and nothing comes up I've put my finger down n there's actually nothing there that I can feel but the feelin of it drives me insane!!! My friend said it could be gerd... I don't even know what that is but does anyone else get this? What could it be? I am 21 weeks pregnant xx
