i have been ttc for almost 3 1/2 yrs. after 9 mos on my own, my dr put me on clomid for 4 mos, which is similar to letrazole. after that I was sent to an RE to discuss options. he ran another blood panel on me to re-confirm my pcos and to make sure nothing else was an underlying cause for not getting pregnant. we also went ahead and did the HSG. it hurt for a couple of seconds, but I was easily able to breathe through it. DH had pretty good insurance coverage at the time, so I only had to pay about $60 for it I think. depnding on your insurance and how the dr bills your testing, your insurance may pay a good portion of things. your dr (whether in your town, or the one in the bigger town), can always submit info to your insurance company to see what your out of pocket expense will be.
after doing the HSG my RE recommended that we do a couple of mini-stim cycles. basically, I took meds that were more aggressive than the clomid, but not near as aggressive for an IVF cycle. I went in regularly to monitor my follicles before triggering the release and then hubby and I DTD at home for a few days. since I was the issue and not my husband, I decided to skip IUI and go straight to IVF. with the insurance we had, I was able to go through multiple cycles at a minimal cost.
I think at this point I have been through just about everything. so if you have any more questions, please feel free to post here or send me a personal message. good luck, hopefully all with work out for you with minimal intervention.
