Iron pills . . Scared !!

Mari🎀 • 1 baby girl avoiding having another for now
So I guess I have anemia , ( I think that's how you say it ) but ever since I had to take iron pills here n there I feel like I can't breath , my heart beats fast n it scares me that when I go into labor , I might die due to not having much blood or scared that I might get a c-section, the point is I want to get my iron back up n my blood good , but idk what kind of foods to eat that have iron in it , does anybody know what foods are good ?
