Hi,
I know the frustration of IUI's I did them for 12 months with no sucess. My doctor was happy for me to keep on going until we did reach a BFP, but I was inpatient and ended up on a IVF course of treatment. Are you currently having one or two inseminations done, that can up your chance of a pregnancy. As long as the drugs are bringing on ovulation and you are having positive OPK's (If not you can trigger o) to pinpoint the best and most fertile time.
IUI's are funny business you hear about people that it works first go and then some it takes alittle longer, I wish you all the luck in world that you will get your BFP really soon!!
