Does anyone use Clearblue OPK's?

I used a clearblue OPK this morning for the first time (I'm on CD 10) & it showed Peak fertility! I don't have any other signs of ovulation though, my CM is creamy & my cervix is firm. I don't get it, could the test be wrong? I did have a MC in December, could it be that my hormones are still settling down?
