Had a blood test last week, picked up results at doctors today. She said levels were low and was i having regular periods!!!! I had to point out to her i am 7 months pregnant before she realised the blood test was for iron levels. Anyway she has prescribed ferrous fumarate which are in a bottle with no instructions and no details of side effects. I googled it and apparantly they are not rated and do not know if affects unborn baby etc..... Should i take them or wait and discuss with midwife? Has anyone else taken these?
