Do OPK's work for women with PCOS?

Hi all! I just finished my first round of Clomid 50mg and didn't test, because I've read that OPK's don't work for women with PCOS. Do any of you think otherwise? I was told that they will constantly show a high LH surge. Need some info before I head out and spend the money.
