Update on my Clomid roller coaster ride(long post)

 I had my follie check for IUI #1 on CD12 and then again on CD15 and was told that there was no difference in size over the course of the 3 days so I wasn't responding to the Clomid.  I've continued the OPK's even though we were told this cycle was a no-go because I just didn't feel like this was happening because I've always been regular until being put on the Clomid.  

I now have a tiny bit of hope for this cycle instead of none...I finally got my surge on OPK today on CD22!!!  I called RE's office and spoke to the same nurse that told me that Femara and TI weren't options for me (I already went off on my rant/rave in a previous post).  She was kind of surprised and told me that I could come in for another follie check today to see if insemination was going to be possible for us after all this cycle, but as luck would have it my DH just left for a business trip this morning and is OOT for the week.  )c:  The nurse said that she didn't want to get my hopes up because OPKs can give anovulatory women false surges...um, I'm not anovulatory and dammit I've told her multiple times how I've always been regular up until being put on the Clomid this cycle.  She didn't even acknowledge me saying this again until a few minutes later when she had to check my file for something else.  She then said, "Hmm, well it looks like you aren't anovulatory!  I'm so sorry I said that, hun!"  WTF?  

Needless to say, I have an appt. next Tues for b/w to check my progesterone levels so they can verify that I did indeed O.  I opted out of the follie check today because we're OOP and it's not like we'd even be able to do anything about it this cycle since DH is gone.  I'm just so happy to have gotten that surge after thinking I wasn't going to O at all this month.  Is CD22 super late and will I need to change the expected arrival of AF by a week since I O'ed a week later?  Has anyone else had super slow follies on Clomid?  The nurse said it can happen, but typically Clomid moves things along faster.  

I feel better knowing that this cycle didn't turn out to be a total waste like we'd thought because #1 I got my surge this morning AND we just so happened to BD last night and #2 this might shed some light for RE for my next cycle if they know that I'm O'ing later than they expected.
