An ovulation predictor kit tests for different hormones than a pregnancy test does. An ovulation predictor kit looks for LH (lutenizing hormone), which surges just before ovulation. A home pregnancy test looks for HCG, which is the pregnancy hormone.
That said, it is possible to use an OPK to test for pregnancy. And they often do show up as positive. But it could be detecting amounts of LH in your urine, because it's so similar to HCG. So a positive result from an OPK is not as reliable as a positive result from a HPT.
