What size is your follicle? I would do IUI. I was pg on a clomid/gonal-f/IUI cycle when I was 32. It can't hurt. You've come this far; sometimes it's easier to move on to someone/something else when you've completed all you could. If it's a decent size follicle why not just give it a go? Many ladies on these boards have gotten pg when everything has gone wrong with the cycle.
