Alright so ive been with this guy for like 2 yrs he left for iraq the end of dec. so thats the last time ive had sex. the last time i remeber having my period is the beginning of may i dont really keep up with it cause i mean i havent been having sex and im not on birth control. im trying to avoid going to the doctor hoping i can wait it out and itll come. ive personally ruled out the preg. thing i would be 6 months and idont look like it at all. if u know what could possibly be wrong or make it so delayed please let me know.
