M.S.
I think many times when a woman so desperatly wants to have a baby, you make yourself believe you are pregnant! I can remember one month so desperatly wanting to be pregnant. I felt sick to my stomache, was tired, sore breasts, all the commom symptoms. As soon as I saw the test was negative, I got my period and the symtoms disapeared. It is not that common to get a negative result when you are pregnant. I am sure it is possible, but unlikely.
