Yes it was a reaction to the HSG, the dye they used, or volume of liquid inflamed my peritineum, apparently! The HSG itself was excrutiatingly painful, I screamed and cried!!
Yes we wondered if there arent some low tech solutions, before they resorted to IUI/IVF. BF said I should get tested for Thyroid Antibodies and NK cells, the latest theory is your immune system can be 'over geared' and go on the attack. This isnt available on the NHS, but it would be much cheaper than IVF! Its amazing we got approved so quick, but I think we will just keep trying naturally for now...
