my iron was in the low end of the normal range during pregnancy, i had taked iron tablets but they made me vomit even more so i stopped. about 10 weeks after dd was born, i noticed i was really tired, then started having panic attacks / getting depressed, when they did blood tests they found that my iron level was 8 (the lowest you can be and 'survive' is 50), so mine dropped very significantly, very quickly. i did have c/s though, and my period started straight away as i couldn't bf dd. but it is something that you can easily keep on top of during your pregnancy, and request that it gets checked at your 6 week post-birth appt.
