Suggest Treatment For Infertility

I AM 22 AND I AM WONDERING WHY I CANT GET PREGNANT? I HAVENT HAD A PERIOD IN ALMOST THREE YEARS NOW, AND WHEN I DO HAVE ONE ITS VERY LIGHT AND LAST MAYBE TWO DAYS, BUT WHEN IM ON BIRTHCONTROL ITS NORMAL ONCE A MONTH AND 5 TO 7 DAYS , ALL I WANT TO KNOW IS IF I CAN STILL HAVE KIDS AND WHAT DO I NEED TO DO TO GET PREGNANT?





THANKS HILLERY
