1. Know your trigger
First of all, you should know the main culprits that trigger heartburn, namely fat, citrus foods, spicy foods, chocolate, caffeine and carbonated drinks. We’re not saying, of course, that you have to deny yourself your cravings, but be careful when you eat them — especially if it's close to bedtime. Eating these foods and hitting the sack can definitely increase your chance of having pregnancy heartburn. Try keeping a food journal of what you're eating, when you're eating it and when you're suffering from the heartburn. If you can find a pattern, then you could very well find your solution!
