Low LH?? Can the top one be positive? Please read woke story before voting

Ok so I know that the test is officially negative but I was wondering if it could be considered positive?? Let me explain myself... I think some people never get enough LH in our systems to get a positive opk, but we still ovulate. I know I do because I chart my CM and bbt and I usually do ovulate around CD25-CD27 so I'm thinking I could mark this test as +? I don't think I will never get a darker one anyway...opinions?? Test is Tesco's own brand opk. Top one from yesterday, bottom one this morning. I'm having mild cramping (mittelschmertzen??).
