2 weeks late.. BFN

Kay
So im having symptoms: waking up to go pee. Waking up hot. Getting hotflashes. Felt sick twice. During sex my stomach feels like pressure. Random cravings. Tired all the time. Moody and emotional. Oh my periods 2 weeks  late and im always regular. But im tested negative on tests! Im so confused. Am I out? Is it possible to be pregnant even with the BFNs?
