20 and purposely trying to get pregnant!

I'm 19 I'll be 20 November, I've been with my bf 3 months; we've been best friends for 5-6 years now and dated once 2 years ago... I know what I want, I know I'm young but I'm ready and so is he... he makes enough money to support me and the baby and have a place for our selfs. I'm also working right now and trying to get my license. Anyone have any advice or stories they would like to share, how you told your parents, how they reacted, if you purposely got pregnant or was it an accident, anything would help?
