Heart Burn??? HELP

Hi guys how is everyone?? Well I am almost 7 weeks out and I must say I am doing good. I have one complant.....I have a constant burn in my chest. It feels like heart burn but I dont think it is because it last all day for a few days at a time. Its all ok as long as I dont eat or drink anything but as soon as I do it starts to hurt again. Does anyone know what this can be?? Thanks Melissa
