On Oct 10th of this year i had protected sex (IE CONDOM) and i think the condom broke or something because i have been more tired,threw up once been a little sick to my stomache. and wanting to sleep more later and later each day? what are the chances that i might be pregnant? i need to know?! i am scared because i have had most of the signs so far like snore nipple (now there a brownish color instead of a pinkish color) and i ended my period on oct 10th so i fingured it was ok to have sex and now i am worried any ideas would be greattt ;-)
