BFP after HSG?

Hi, husband and I have been trying for a few years now. Started seeing our specialist in November. We have now had 4 failed IUI's. I take clomid along with HCG trigger.  We just had the HSG "dye test" done on June 27th.  No blockage!  I've heard that sometimes women get pregnant shortly after having the test done as it can clean the tubes, so to speak... I was just wondering if anyone here has any success stories following the HSG test. Thank you :)
