Although I've been lucky so far as to not have constipation (touches lots of wood) my iron levels have been a bit low, and I'm dreading them dropping any further, so that I have to take the dreaded iron tablets!
My friend had terrible constipation when pregnant, and she too swears by prune juice. However, she drank some at work one afternoon, and only just made it home, if you know what I mean! So if you do take it, go easy, as it really really works if you take too much at once!
Hope you feel better soon.
