An old wives tale said that when you have heartburn when you're pregnant then your child will have a lot of hair when it's born... I don't think the two situations have anything to do with each other. Yes, acid reflux is the newer medical term for heartburn. Years ago we used to take baking soda in water (somewhat like your alkaseltzer). Try drinking something like canada dry ginger ale or upper 10 (do they still have that?). Try also eating bland foods and changing to a vegetarian diet. Also, don't eat after 6PM in the evening. And, raise the top part of your body slightly when you sleep, and sleep on your side. If you can't get rid of the heartburn, maybe now that you've been pregnant you might be alergic to something new, or, the foods you're eating have a preservative in them your body doesn't like. It could go either way, either your body has too much acid in it or not enough, both react the same in giving you heartburn. Or, try "beano" before you eat food and see if that makes it any better. If you're still getting heartburn and it's coming up on you, then get to a doctor as it may be a more serious problem. It's premature to scare you but when the body has too much acid it causes cancer (a new study says). So you need to reduce the acid. If you're drinking coffee, tea or soft drinks then switch to just water for a while and see if that changes anything.
