Ugh! I know the feeling. Hang in there girl!!
We did 4 medicated IUI's and are considering IVF or adoption at this point. I never want to hear IUI again!! lol We never did the natural IUI's and I'm glad, seeing that it didn't even work with the medicated, =) We did 3 cycles of Clomid and the 2nd and 3rd with Femara. Then we did our 4th with a combo of Letrizole (basically Femara) and Gonal injectible. No luck, =( My husbands sperm count was low though on our 4th IUI which makes me wonder if IVF would do the trick. So thats where were at, at the moment. Limbo!! hehehe...
Good luck with whatever you choose to go forward with. I'm always on the more aggressive side and would ditch the naturals after this cycle, but I understand others don't feel the same way. <img src="i/expressions/face-icon-small-wink.gif" border="0"> Its a roller coaster no matter what you choose, Good luck!!
