Hi, like you I had been trying for almost two years when I had a laparoscopy and the dye thingy as well. I was also told that I had one partially blocked tube, but that the dye had managed to get through it. Prior to this, I had like you partial bleeds - well just bits of old blood in between periods, and an irregular cycle. I was not recommended to have a D&C, but I did get pregnant shortly after having the laparoscopy etc. I pretty much got pregnant the month after the consultant gave us the all clear, so I think by that point stress was also a factor.
I hope it all goes well for you, as it did for me - I now have two boys (age 7 and 6) 13 months apart, as we took advantage of the fertile period after you have a baby.
