My younger sister who is 26 yrs old has not had her period since Jan 08, she is sexually active with her live in boyfriend, she has taken multiple pregnancy tests (from stores), she is not on birth control, she does have an appointment coming up in a few weeks, my question is could there be something wrong with her, is it normal to
not get your
period that long and
not be
pregnant. Has anyone ever had this happen, if so what could it be.
