Teen pregnancy at 17

Paige
Hello glow users! Me and my fiancé are considering having a baby, I know you all will say I'm too young but I am honestly ready. I have a nice flow of income coming from myself and my fiancé. I was wondering if anyone could help me with a few questions I have! (: I was wondering do you always have spotting after conception or no? Also how soon after conception do you notice signs of pregnancy? Thank you all!
