How many IUI procedures with injectables do you do before it's time to move on?

Depends. Iui(intrauterine insemination) is a procedure that has been utilized to help couples become pregnant. Unfortunately, no one can make that decision for you...The only rate limiting factor would be financial i suppose. However, try this...Take some time away from the stress that the experience is generating and try just to enjoy the art of conception; plenty of children were conceived this way.
