Hi Loops. We have exactly the same thing. DH's soldiers are up, then down. We had our 3rd IUI on Wed last week and like the nurses have said....we have 'Unexplained Infertility'. She said this is more annoying because they can't actually pinpoint why we are having trouble trying to fall pregnant! Arrrgghhhh!!!! Anyhoo GL with everything - hope you have a BFP naturally!
