Hi Karena,
Welcome aboard! Never did IUI ourselves, but i think it is a far kinder option to your body, so thats good. You might find that you cope really well with the meds. I honestly did really fine on them. Hardly any problems, and in all honesty i rathered the injections to taking the nasal spray - no kidding! The injections are fine.
Good luck with it all, but be careful - posting here can be addictive!
