First time mommy

Krystal
I'm 20 years old and my boyfriend and I are a excited to have the baby as well as a bit worried. We planned on having our baby and we had been trying for about 4-5 months and now I'm finally pregnant. I'm due jan.28th. 
I'm just worried how to exactly approach my parents on the situation and how my boyfriend and I want to live together and get married.
