One follicle with at least 20 mm sounds right on target. You can trigger shot to make sure u release if you don't want to wait for surge.
Don't fret too much.. it only takes 1 good follie to get pregnant!
The last time I did clomid, my second cycle only produced on mature follicle and one other follicle that was a little under (17 mm I think), and I ended up getting pregnant with twins!

i am not really sure.
I did IUI this month with clomid+HCG. I have done clomid for 6 cycles already and usually only have 1 or 2 dominant folicles. This month i had two 22 and 23 mm - had HCG and then IUI the next day followed by DTD 12 hrs later.
GL to you. Fingers crossed!
