Hi naenae

I'm sorry I don't know anything about tubal issues or natural iui cycles.

I have had 3 succesful IUI's and 2 failed IVF stim cycles which is really quite confusing.

But when I have had my IUI's in the past I have only been on a very low dose of FSH to try not to produce many follicles. I know its different for everyone but I barely noticed the effects of such a low dose.

I also didn't find the speculum overly uncomfortable as I have found FS's to be quite skilled with them and I seem to have a lot more cervical mucous at the time when they do the iui so its not too bad.

I hope that helps. It can be a confusing time and I always hated the thought of wasting time if there was something else that needed to be done instead - best of luck!
