I'm still not ovulating...

So 2 years trying... I had 1 round of 50mg of Clomid...and i ended up coming on super early on CD24 after not getting any positive opk. So now im in round 2 uped to 100mg of Clomid and again no positive opk. Im just kinda waiting around for AF to arrive now so I can ring my consultant again to see what's next...but tbh Im not sure i can be bothered at the moment -im just so tired and it just all seems too much right now. Wondering if anyone else has had a similar experience of clomid not working?
