TTC #2 After Successful IUI with #1

Jeniece
We've started TTC #2 after successful medicated IUI with #1 (that IUI followed laporoscopy and ovarian drilling for endo and PCOS).  I had the surgery and drilling again this past February 2014, and we're hoping for a BFP without meds and IUI this time.
​Any tips or success stories?  The thought of going through this again hurts my heart nearly as much as the first time!
