Is there any OPK that is best for someone with PCOS and on Clomid?

I am on day 2 of clomid and my doctor told me to buy a OPK to test at home. I have a 150 dollar monitor already but since I have PCOS it has trouble reading and always says I have high fertility when in fact I never actually ovulate. I also read clomid can mess with the OPKs too. So I am curious, is there any brand out there that will work best in trying to detect a true surge?
