Any sugestions anyone? i eat about 5 oranges a day because i have a craving for them i drink alot of water & have bren flakes for breakfast but i am so constipated its agony. I dont go for 5 days at a time. Im 12 weeks pregnant. I was thinking about taking some iron tablets because unlike most people they help me go every day why i dont know, although my doctor hasnt said i need them can it do any harm to take them?
