No positive opk on clomid yet

So my first round of clomid I ovulated got a positive opk cd 16 and did days 5-9. To try to push up my ovulation date I did 3-7 this time @100 mg and today is cd 14 and no positive opk in sight not even high readings on clearblue. I thought taking the clomid earlier would make you ovulate earlier I guess not :( if anyone has some advice please comment
