My last period started on September 3rd, and I haven't had one since! I have taken 3 pregnancy tests and they all say negative..I am also a type one diabetic and wondering if maybe HTC just doesn't show up in my urine?!!! I have never been this late, and I am also feeling very tired and have mood swings...I am either starving or not hungry at all...I don't want my doctor to think I'm being crazy...I am beginning to think maybe  I am crazy! PLEASE HELP LADIES!
