Thank you all for your information, it has been very helpful.

I am going to do some research now into finding a microsurgeon to perform the operation to unblock my tubes. Although it may be useless, there is no harm in trying I guess. I may be in that 2% of women that have miracle conceptions after being told that there is no chance.
After spending the last three days crying, your thoughtful and helpful words have changed my perspective on my situation. I will try the op first and if it unsucessful then I will try IVF. Either way I still have a chance to conceive and thats better than nothing.
Thank you all again, i'm feeling better about everything already.
