tommygirl - heartburn is a sign of pg, but it is also just intergestion. I quite often get heartburn by eating particular foods, or eating too close to going to bed, although when i was pg, i got REALLY bad heartburn, but it didn't start till the 4 or 5 wk (i think). I find the best thing to use is quickeze chewables or if you haven't got any, have a glass of milk, as this will help cool the rising acids from your stomach and neutralise them.. HTH's
