Hi Morgan
I agree, it helps so much to be able to talk to others who actually understands. Many people out there are completely oblivious and can be very insensitive.
If I understood correctly, my FS said that if it turns out that my tubes are completely blocked, then IVF is the only option. I recall him saying something along the lines of "for all treatments, except IVF, we need your tubes in working order" (I'm translating now). He doesn't seem to think that mine's blocked, but we'll know next week. It really seemed as if he's suspecting endo instead, which he described as a possible cause of inflamation that may effect the egg quality.
So for now I'm just trying to stay calm and not get worked up about the many possibilities - rather wait to see what's going on inside.
Have your gynae/FS ever suggested doing a laparoscopy? Mine said that he likes to take a conservative approach and check those things before moving on to more expensive treatments. Otherwise you spend a lot of money on 3 - 6 IUIs, just to find out later that something was wrong from the beginning. I'd rather do that than go through more BFN cycles, because the emotional component to this also takes its toll.
Hoping that AF doesn't make her appearance for you this month.
