antidepressants and pregnancy

I am a 21 year old female. I take an antidepressant (Effexor) 75mg a day. I am unsure about some info I read on another web site. It said do not take effexor if you plan to become pregnant. I do not plan to become pregnant anytime soon, but would like to have children in 5 or so years. Is the effexor going to effect my ability to become pregnant in the future? My doctor has told me nothing about this. Any info anyone could contribute would be greatly appreciated. Thank you.
