My FS said 20% chance for IUI and IVF (and Clomid) - and that was per cycle. Not sure on the multiple transfer though. But he said the chances were better because we were younger and fit and healthy etc (we're still both under 30). Basically he said that while the odds were the same, the mechanisms were different and some methods work better for some people. So he starts with the least invasive (OI - clomid) and progresses through.

AFM, I have a feeling I did ovulate this week. Twinges and CM would say I did anyway. So now we wait for AF (or not if we're lucky). If AF visits we'll have another natural cycle before the IUI in the new year. I'm happy with that, if the naturopathy gets my cycle relatively normal that sounds even better! However, we're definitely keen to maximise the chances of pg, so we'll be going ahead with IUI when we can. I can feel it - a pg for me early next year! OP - you've lead by example!
