Food: Fully cooked Hum/Cockles (do consume in moderation) Spinach Broccoli Tofu Dark Chocolate (yummmm) Fish (do check which fish because of fishes contain high in mercury and its not safe to eat during pregnancy) Raisins Peanut Butter All of above, do check how many mg of iron do they contain and how much does your body need okie! I got no recommendation on pills, might want to ask your gynae for recommendations.
I think for supplements you ask your gynae. Because iron supplements can cause constipation For food wise you can try eating spinach and beef
