Something strange.

Are you stressed from this or were you stressed before it happened? If it was before this happened then it may be due to the stress you are under. Secondly, has the time that your period was expected passed yet? If so, you might want to go and see your doctor. If not, I would recommend waiting to see if your period comes and if it doesn't, then to go see your doctor. Good luck.

Stress  does  play a big factor  when  females  have their periods  due, Stress can  make a  period  more heavy  than usual ...Also  being on birth control can also  make your period  quite  different...Also birth control  can  stop periods ...it  can make  you  have period  issues ...If  you  can't  get  adjusted on your birth  control ...Than ask  your  doctor  to  consider the  Depo Shot ...My  cousin was  on  Depo Shot  for birth  control  and  it  does  stop your  periods ...You only  get  the shot  Once every  3 months ...Yes , it can  cause  a little  weight  gain  But  I   think  it's worth  it...Mostly  weight  gain  is  due  to  over eating  And  not  watching  what  you  eat...In order to  go  on the  Depo  shot ...You  got  to be on  your period  the  day  you  get  it
