me
first get checked out by your ob.. and second no it is not a definate sign of miscarriage.. being a mother of two.. i have had quite interesting pregnancies myself..but i remember distinctly with my first i swore up and down i was going to get my period and it never came i had cramps and the whole nine yards..the ob.. figured my pain was from the stretching of my uterus.. all i can say is prepare for the worse and hope for the best.. best wishes.. me.
