last month in may...i had brown period for a long time like 2weeks... and i was going to go see the doctor but i thought it was nothing and my aunt said it should be just a change of my hormones since i am growing and only 13 turning 14 in october... i cant be pregnant because i have never had sex before and never even kiss a guy before so im not pregnant. and this month (june) my period was suppose to come on the 21st but it didnt. could it be because last months period started at the end of may and it ended at the begining of june?? thanks for all the replies :-)
