IUI procedure

Has anyone ever had an IUI procedure ? Are there any tips on how to have a successful IUI?

I had the procedure a few months ago— I experienced what to me felt like heavier bleeding compared to spotting. I have never spotted a day in my life so I really do not know if that was spotting or not. The staff where I go are not all to friendly and when you ask a question they look at you as if you should already know the answer.

Next week I should be going in to have a procedure and I’m just praying this time it will take ! Any tips for a successful IUI please comment !!
