Pregnancy Vitamins

Hi, I'm currently at 20 weeks pregnant and I'm taking Iberet Active + Caltrate + Anmum 1x a day. Meron pakong riseta na NatalWiz pero d ako makahanap laging wala sa Watsons and South drug and Mercury nearby sa area namin. Okay lang pa sabay sabay ung Natalwiz, Caltrate and Iberet? Kasi nagpatong patong na riseta saking ng OB ko.
