Ay, that's a good question sis! Hindi ko sure kung kasama talaga sa Obtrene ang iron, pero maraming OBs naman ang gumagawa ng separate prescription para sa iron supplements kaya baka yun ang setup ng doctor mo, sometimes they want you to take it at specific times or with certain foods para mas mabuti ang absorption. Best to ask your OB directly kung bakit walang iron sa Obtrene, or if kailangan mo talagang separate iron supplement, para sigurado ka lang with your specific pregnancy needs.
