Hay, congrats sa pregnancy! Okay, so ang Foralivit ay iron-based vitamin kaya tummy ache after drinking it is super common, lalo na pag on an empty stomach, a few of us moms nag-experience din nito nung pregnant kami. Try taking it right after you eat, hindi before, para hindi gaano maka-upset sa stomach mo, and drink lots of water with it din, that helped one of my friends talaga. But since it's causing you discomfort pa rin, best mag-check with your OB nalang para ma-adjust yung timing or brand if kailangan, basta sigurado tayo na okay lang sa baby mo.
