Oh my! Maybe tmi

So I have now been constipated for like 2 weeks. It is so painful now to the point I can't sleep the pain is from my hips to ribs on the sides and across the Base of my back. Well with still being awake at quarter to 3 in the morning I'm thinking what could be causing it?? First conclusion pregnancy then it hit me could it be the my multi vitamins as these new ones have iron in them?

Does anyone else get similar symptoms with taking iron supplements. This is the first time I've taken them.

I think I might give them a miss for the next few days and see if it helps.

Sorry no one to ask and thought I would ask you ladies.
