advice needed!!

Hey guys okay so I need some advice and support from some non judgmental people me and my fiancé are young we got engaged on my 19th birthday after being together for 3 years I am 19 and he is 24 I love him with everything I got and he's so prefect he is very respectful of me and my family and he protects me as if it was his last day with but yet he never gets in my way of having a life he has no problem with me going out with my friends and he super supportive of everything I do our relationship is very healthy and just like everything I've ever wanted recently within the last 3 months we have started trying for a baby I know I young but it is something I've always wanted I didn't have a great childhood and I have a lot of family problems  I guess I'm just worried about what my family would do if and when I have a baby I'm very scared about what are your thoughts?
