Thanks everyone for your thoughtful replies. It's such a help to hear your opinions when we are just so confused and in shock still.

Farmgirl - IVF IS a stressful decision and I really have no gut feeling about where to go. One minute I'm thinking, "No, I want to try a bit longer naturally" and the next I'm saying, "Who am I kidding? It needs to be IVF so the sooner we start, the better"

Jellybean - I think DH will take the vitamins no matter what. Congrats on achieving your pregnancy first go!

Loops - Wow, that's a huge variation in sperm count. Maybe DH should have his tests repeated to see if there's any difference??

Beata - I am trying not to blame DH, but part of me does feel it's unfair that I'm the one who'll have to go through all the invasive IVF stuff when there's nothing wrong with me in the first place! It feels unfair and almost wasteful even. And I know that DH feels like everything is his fault, and I feel awful that part of me is upset with him too!

WLB - Yeah, it's so hard just trying to get my head around everything, and it's all happened so quickly and taken us by surprise.
