Ay, common yan mama, especially around your third trimester, a few of us were switched din from folic acid to iron supplements kasi by that time, yung baby nyo na talaga ang nangangailangan ng iron para sa delivery at postpartum mo na rin para hindi ka anemic! Ang ascorbic acid naman ay tumutulong sa absorption ng iron kaya paired sila, so that makes sense with what your doctor prescribed. Since 35 weeks ka na talaga, best talaga na i-confirm lang sa OB mo kung bakit specifically na-stop ang folic acid sa inyo para sure, pero generally normal lang yan sa pregnancy journey!
