IUI #1 is set

I had my monitoring appointment this morning.  The nurse found 1 mature follie and 2 that may be ready by the time the IUI rolls around.  My lining is a little thin, but the nurse said it should thicken up rather quickly.  So here's the plan:

• Trigger tonight
• Mr. MBC has to be at the RE's office at 7:30 Sunday morning to provide his sample
• IUI should be around 9:00
• Start progesterone on Monday evening

I'm super excited that this cycle is working out.  I'm trying really hard not to get my hopes up, but it's really hard.  Fingers crossed that this is it!!
