OK my period is nine days late I’ve never been this late without being pregnant today I took a clear blue digital test and it said not pregnant I have signs of being pregnant sore breast stuffy runny nose miss. By nine days food taste funny heightened smell and Temp is kind of high 99.2 and up what could be wrong with me I’ve never had this happen to me before could I still be pregnant or no should I contact the doctor or what also been having dry throat and headaches
