question: I just found out I have low iron, was told my number is 10. I don t have anemia though, but my doctor put me on iron supplements to prevent anemia. I should have started my period 5 days ago. I have had all the regular pms symptoms - bloating, bad sleep, tender breasts etc. I ve been spotting for 2 days now, but it feels like my period just doesn t want to start. Can this be due to starting the iron pills?
