Probably a seriously silly question, but I'm a worrier, I'm 18w pregnant and suffering with heartburn, been drinking milk flat out, today I've had 2 full cartons of milk (the small ones) I think it's a pint per carton? So a total of 2 pints... I know there's medication out there but I find milk is the fastest relief for me & gaviscon etc makes me sick , anyway would this do me any harm?
