Hi, this is my very first post here and i thought i would reply to you! On my first clomid cycle in Jan this year i took my clomid cd5-9 and i didn't O until cd26. My P4 was 55, 7 days after O.
I have heard that clomid will make some people O later than usual, i'm just glad that i O'd. Hoping this cycle is as successfull but hoping to O a little earlier as well.
I asked my doctor the same question about the late O and she said that every cycle is different and you can't predict it.
Hope that helps.
