I usually run 33-34 day cycle ..AF was expected to start yesterday 11/21 on one APP and expected to start today 11/22 on this app. Ovulated on 11/7 .... Anyway I took a pregnancy test yesterday night 11/21 - was Negative.. I don’t feel any signs of AF my question and hopefully I received some feed back ... should I test again or has anyone ever tested negative on expected start date and later had a positive test!???? Cycle buddy maybe
