Should I got to the specialist or get a second opinion?

I have been trying to get pregnant for 16 months. At a year I started getting tests done by my OBGYN to see why I have been unsuccessful. Well I got an HSG test done and she said my right tube looked fine and that there might be a tiny bit of a blockage but that my left tube looked blocked towards the very end of it but even though it was block, the ink went into my ovary. So she did a hysteroscopy yesterday and she said she could not find any scar tissue, cysts, or anything and they looked open. I am like how can they be blocked if the ink went through? Well I think I am not ovulating. I had 14 day cycles before I went on the pill and after that I consistently had 18 day cycles. Well I started taking vitex and now my cycles are 24 days long. Well I test for ovulation every month. I have a $300 OPK monitor and I take my temp every morning and I check my CP. And NOTHING points to ovulation. I never once got a peak ovulation, my temp is always low and my cervix is always low. So I know I don't ever ovulate. Well she is adamant that she thinks I do ovulate and that I ovulate when I bleed and that's why I had a period twice a month. So she wont give me clomid and just referred me to a specialist. So should I go to a new doctor and see what they think or should I just go to the specialist and run more tests?
