Trying forever and now I'm not ovulating??

I've been Ttc for about 17 months now and nada! Last month I went in after being on clomid for 5 months to find out I didn't ovulate. They upped the meds its day 19 of those flashing smileys with no end in sight. Will it ever happen for me? Am I broken? Has anyone had a similar path or are they going through this? Could really use a sister, someone who is or has gone through this.
