Hay, normal yan sa pregnancy, sis! A lot of us moms experienced that acidic taste, lalo na around first and second trimester, it's usually hormonal changes plus the way pregnancy affects your digestion kaya parang laging may lasa ng metal or sourness sa bibig. For relief, marami kaming natry: frequent small sips of water, chewing sugar-free gum, or eating citrusy fruits like calamansi actually helps some of my mum friends more than you'd think. But since you're still in early pregnancy, best to mention it sa OB mo just to rule out anything else, para peace of mind lang.
