Ay mama, ang best person to ask talaga about timing and safety ng supplements ay ang OB mo mismo, kaya siguro okay lang yan since prescribed niya! A few of us moms nandito din na prescribed ng primrose ng doctor namin early, at they explained the reason para sa amin, so maybe pwede mo itanong ulit sa OB exactly what she's aiming for with the timing? Lagi naman may purpose kung bakit nila ginagawa yan, trust her kasi siya ang expert sa pregnancy mo. Good luck mama, you're in safe hands!
