I've been taking lactulose prescribed by the doctor and have stopped taking my prenatal suppliments as they contain iron which is known to slow the whole process down. I have been told by the midwife that I'm slightly iron deficient so can't stay off the suppliments any more. Does anyone have any advice? Thought about taking a normal laxative but the one I have says they have no evidence on its effects in pregnancy. It's Bisacodyl. Thanks...
