I have been having what I think might be early pregnancy symptoms. for the past two weeks I've been cramping a little and feeling nauseous and tired all the time. I went to the doctor today and she took a pregnancy test, it came back negative but she is convinced it's too early to tell. so she is going to do a blood test. I am so nervous that it will be negative- this feels so right! also, my period is late. my last period was August 23...
