IUI, again or IVF?

Jessica • ttc for 4 years. Have 1 tube open by lap surgery. Did 2 IUIs and no luck. IVF June 2016. I need to just relax, 😆
Having my 2nd IUI on Thursday the 25th. Did Clomid again this cycle and a trigger shot later today. I wonder how many cycles most do on IUI before deciding to do IVF
