Ttc with polycystic ovaries!

ttc for over 2 years and I have been diagnosed with polycystic ovaries! My doctor now wants to do the dreaded test on my Fallopian tubes to see if they are ok! I'm absolutely petrified of having this test done and I was hoping for it to be a last resort! I'm wondering if I should wait to do anymore awful tests, start actually taking the meds like metformin or clomid and see if I get pregnant? Any advice appreciated
