Any thoughts ladies???

Im trying to put off testing until Im late for af in one week, but to help ease my poas addiction i took an opk internet cheapie. While it wasnt positive, it seemed much darker than it should be at this point in my cycle. I know they say it will be blazing positive when your pregnant, but do you think because its early it was that dark, just not pos? I feel like in my previous cycles it was an eye squinter to even see the second line. Thoughts?
