Help. Any insight is good!

So I'm 22 and the only reason I'm asking this on here is cause I dont have any female friends. And I need insight. Me and my fiance live alone together and we work. We aren't using protection of course we want to have a baby but we don't care when. If it happens cool if not that's OK too. But I have baby fever and I really want this to happen. I'm 2 days late on my period. And the whole reason I got this app is to see my fertile days. And we had sex a lot during my week. So maybe we actually did it this time! I've had some symptoms but right now I'm putting them on the back burner. Any thoughts?
