Nervous but excited!!

Here's my background:  29yo and TTC my first with my amazing husband.  Trying for a year a half with PCOS and 3 cycles of failed fertility treatments.  I followed up with my RE today and he wants to try IUI this cycle!  My husband and I are very excited for this next step and our RE seems very optimistic.  Im nervous about the process and starting it so quickly. I've been spotting the last 10 days so we did lab work today to see where I am in my current cycle and figure out which specific route we will take.  If there are any other IUI ladies out there, can I hear your stories?   Hoping for my 2017 baby!
