I can't swallow pills and floradix makes me nauseas so my midwifes gave me iron shots. They were coming a couple of times a week to give me a jab in the bum. I still have big black marks on my arse cheeks that look like bruises. They lasted for nearly two years after the shots when I had them with DD1, am waiting to see how long they last this time. They didn't really hurt any more than you would expect from a big needle poked into your tender cheeks
