Hi mama! Honestly, I'd suggest checking with your OB muna para sure lang, kasi importante talaga ang calcium supplement na ino-take mo during pregnancy at need mo ng professional approval para sa specific brand at dosage na safe for you. A few of us pregnant mums always ask our doctors first bago bumili ng any supplements, kaya mas peace of mind talaga! Your baby's health is priority, so better safe than sorry with these things.
