wanting a child

I am 25yrs old and me and my husband have been having unprotected sex for a few years now. I am on no type of birth control and we have had no luck in becoming pregnant. The one thing that really scares me is that i wont be able to have a baby. See i dont have a normal period, i can go months with no sign of one. So im thinking now that im infertal and its killing me! Can you get pregnant even if you dont have a monthly period? I take prenatal vitamens along with folic acid i dont smoke and i rarly drink. Can anyone give me advice or has anyone been in my place before?

Hey, yes it is possible to get pregnant with no periods I was just watching a show today about women who havnt gotten their periods for a good 15 years and they got pregnant, so I wouldnt give up :) try watching the show, its on TLC called I didnt know I was pregnant.
