I did ask if I was going to ovulate the 21 mm one and the RN just said no and not to worry about it (she said they want between 19 and 24 mm to be considered mature). I'm also thinking it has something to do with the Lupron. I really need to get better at asking why something is being done (or not done). I get so focused on asking about my next steps.
Thanks for also explaining why some people do 2 IUI's. Very interesting - I will definitely ask about this. I can see why people BD the after the trigger shot.
