PP, I'd suggest you email Dr S and ask. I think that he'd want you to start at 10mg at the beginning of the cycle, and then increase to 20mg and EPU/transfer (although we did ovulation for my natural FETs). But... I really couldn't say for sure that is what he'd do. For me, it was a situation of adjusting the prescription that another specialist had given me rather than starting a new drug.

As far as I know, it should have no effect on ovulation, but different drugs effect different people in different ways. Small example - I have to take my prednisone in the mornings. My rheumy prefers his patients to take it at night so that there's some drug in your system to overcome the morning arthritis horrors. If I take it at night I simply don't sleep at all. Very unusual side effect, apparently, but even when we tried a split dose - one 5mg tablet at night and the rest of my dose in the mornings, I still didn't sleep.

Anyway, best to stick with the safe side of things and email Dr S.
