I am 25yrs old and I have always had my period on time. I have two kids, one 8 and the other 3. I have had three miscarrages before I had my son that is 3 now. I am not trying to have anymore kids but I believe that if it happens then that is Gods will. I have been to a pregnancy clince three time's to take a test and two home test's and all said negative. Is there a reson? :?
