I was told with day 21 progesterone that you're looking for a result of 30 or more, so 66 is great. I don't think there's any link between higher progesterone and multiple births, so no need to worry there
Research shows that if clomid is going to work for someone, it will work in the first 6 cycles, so Naty I'm pleased to see your consultant is already getting the next stage planning in place sensibly.
ccpink - I had an internal at my first consultation as well, which threw me a bit! I'm quite an old hand at them now though - well don't for coping. Good that they're testing your DH as well, always good to know how he's doing as well, as it takes two to tango! Will they scan you during your clomid cycle, or just use the blood tests to check everything is OK.
Peanut - should have answered you earlier, it is quite normal to get a +ve OPK on multiple days. The day you count is the first day you see the +ve result.
I'm hoping my ICSI will start early in the new year - waiting for the nurse to call me back at the moment for more information.
Hugs,
Artoo.
