Hay, try Watsons or Generics Pharmacy, a few of us have had better luck finding specific OB brands doon kasi mas maraming stock ng iron vitamins, lalo na yung prescription ones like Hemavin-OB! If still wala, call your OB's clinic kasi usually may partner pharmacy sila or pwede nila i-recommend yung available na alternatives na same strength lang, importante lang talaga yung iron during pregnancy kaya don't skip it ha.
