I had my CD 10 u/s this am. The follicle ( only one

) is 24mm! So we are triggering tonight for an IUI Saturday morning.
I have scoured the Internet for anything about follicles growing too quickly, and there is nothing! No reason.

so we will see.

I think they failed to notice that I was already working on a dominant follicle before starting the stims (my CD 3 E2 was weirdly high).
Hopefully your super-follicle has a super-egg ready to go and the trigger does the trick for you: good luck Saturday!
