Me and my fiancé have been together for 3 years now, I have not had birth control for the past 2 years, we have never prevented having a child but never planned to have one! Nothing has ever happened! We just started within the past month to have a baby. I was supposed to start my period Thursday and still have not started when should I take a test? Or should I wait it out to see if I start soon? I'm new to all of this.
