TTC please help

Amanda
I'm 25 I'm trying to get pregnant by my bf of 5yrs i have irregular period it's so bad I go 3 months without a period! I've tried provera that's helps me to get a period and I tried clomid for about 1yr & 1/2, I did so many exams and labs but the only thing I didn't do is an HSG!!! My first attempt for the HSG the procedure got cancel from that I lost faith! my bf works out of town and I only get to see him on the weekend most of the time, he have a son from a past relationship. Can someone give me any tip or recommendations please I get frustrated and depress every time I think About it!!!!!
