WLAB - I would not be too concerned. Just a shades said, there should be no spillage of the sample, as the cervix closes after the procedure and holds it in there. If you feel wetness, it is most likely due to where you are in your cycle (EWCM), which if anything, concludes that timing is spot on! On my 1st IUI, I got up straight after the procedure, went shopping etc, and that month we got a chem preg. This IUI however she left me to relax for 5-10 mins due to the cramping and general uncomfortableness that I was in.

I am wondering why your clinic has not ordered a prog test or day 21 test....can you request from them? The point of this test, checking progesterone, is to confirm that you have in fact ovulated, and that your prog levels are high. OP has some detailed notes on this topic in this thread if you would like to look back a few pages.

Shades- a 12mm follie is great. Better one big than than lots of little ones. 2mm growth a day means you are looking at fri/sat so not too far away now.
