1st round of clomid

I just finished my first round of clomid Monday and ever since have done a opk, but it seems as if I'm still not ovulating. I've only had one period since February, found out I have PCOS in late October, tried metformin out (to try to start my periods), since that didn't work the doctor put me on clomid. We've been TTC since February of 2015 and these are the first OPKs that I've done. Maybe I'm not reading them right? :-/
