NEWBIE QUESTION :)

Kimmy • God hear our prayer, see you on JULY 2016 Baby Martinez <3... Sweet peas :)
Hi I'm totally new here and TTC for weeks now! I've been on BC  for 3 years and finally decide to stop few weeks ago. My boyfriend and I are ready to have LITTLE U.S. And both of our family is so excited about this. 
I'm just wondering, how long it could take for us to get pregnant? Months? Years? And for taking BC for three years does it messed my fertility???
PS: AF arrived on time, so this is not my month :( BABY DUST TO ALL!!
Ps
