Iron pills make me sick?

So the other day I hadn't ate anything all day until 4pm (I wasn't hungry) and when I got home I ate a small bag of chips and afterwards I decided to take my iron pill (first time taking it and i took it with orange juice) and after about 30 minutes I started feeling nauseous and puked. Does iron pills cause this for anyone else? I've felt fine since then. They're only 28mg. I haven't taken anymore since then either because I don't want to puke again. Was it because I hadn't ate all day?
