stress can cause your period not to come... also if they were messing around and there was any contact (like pre stuff) then there is still a chance to get pregnant. that happened to my best friend when we were younger. have your friend take a test to ease her mind... go from there.
stress
It is possible that she's pregnant, but no one's going to be able to tell you what the chances are.
She should take a pregnancy test and go from there.
well i would still get a test to be positive but i don't think she is if she got it last month...you can skip your period with out even having sex and it lessens the risk that he didn't c.u.m so i wouldn't sweat it to hard....just buy a test and double check.. Good Luck!
