***WHAT NEXT LADIES? 2 m/c's, no luck since, HSG?

I've had 2 miscarriages -- had all testing done except HSG & Sperm Analysis. I had a saline ultrasound where they look at uterus structure and blood tests for everything that could be wrong and genetic testing for me. My doctor said there is no point in getting HSG or SA since I've gotten pregnant twice. I've been TTC almost 2 years and it's been 10 months since the last time I was pregnant. One miscarriage was natural and the second was a missed miscarriage that my doctor tried to induce with pills but that didn't work so I had a D&C.; I just think there could be something wrong with tubes or semen and we should check it. I'm currently on clomid, had two rounds unsuccessful and about to start the third. Should I ask my doctor to do these additional tests? I'm still seeing my OBGYN not a RE. Any advice or experience would be appreciated.
