5dpo got a positive ovulation test what does that mean?

Elevated luteinizing hormone. There are several possible answers to your question. First you had your ovulation wrong and in fact you going to ovulate five days late. Second, you had it wrong the other way and in fact lobulated earlier and the positive ovulation kit is actually registering HCG that is to say you are pregnant. Third, you are actually not ovulating and have chronically elevated luteinizing hormone levels such as occurs often in pc os, polycystic ovarian syndrome.
