u have all the sypmptoms of early pregnancy reading that list makes me feel like i'm listening to myself complain before i found out. i'm six and a half weeks and i feel all those and more. you can get neg. and still be pregnant it happens all the time. wait a few days, take FIRST RESPONSE early pregnancy test it can detect only 4 miu/ml of hcg, which usually the amount a pregnant girl may have 4 days before her expected period. seriously, buy an early pregnancy test u may have taken a standard pregnancy test that detects atleast 100 miu/ml in which you don't have enough by now. good luck<3
