Acidity and heartburn are way too common during pregnancy. This is a reason why antacids are prescribed during pregnancy routinely. There is a host of diet rules you need to follow to keep acidity in check like eating small meals cutting down on fats or foods that are hard to digest having early dinner taking a stroll after a meal to aid digestion etc. However at times we feel too lazy to follow diet guidelines or even pop an antacid. And pregnancy with its own ups and downs can make you too moody to do the right thing at times.
