I tool a wondfo test which is attached. It came up with a pink line within 2 minutes it's not blazing but not a squinter ( looks pinker in real life) my period isn't due for another week. My issue is I've took another test 3 hours later and it's negative. I've been taking tests the last 2 days which have been negative except that one test. Is this a horrible evap? Been ttc for 7 years
