I've Wanted A Baby For Oh So Long... Wanted To Be A Mommy.. I've Waited And Prayed And Asked Why And Still Nothing. This Month Has Said A lot For Me. I Lost My Grandma On The 15th Of July And I Had NO, I Repeat No Sexual Relations Last Month Of The End Of The Month Before. But Yet I Still Have No Period, Aunt Flow Hasn't Even Showed The First Sign Of Coming... and It Breaks My Heart, I Kinda Think I Am Not Fertile And Cant Have Kids Or Something Is Wrong... I Just Cant Bring Myself To Go To The Doctor Though :( I'm Scared They Are Gonna Tell Me Something That Is Gonna Rip Me Apart And I Cant Have That Right Now. I Already Feel Alone And That The World Is Against Me... Any Advice??
