TTC in 2017

So me and my SO have been together for 3 1/2 years! This may will be 4 years and in 2017 it'll be 5 years! I'll be 19,and he'll be turning 22 that June! We live a hour away from each other but that's never affected our relationship. It's just always been that way and we see each other Friday-Monday because I'm at school and he's working through out the week! In 2017 I'll be finished high school in June and I was suppose to be finished last year but I stopped going to school for two years due to anxiety so after this year it's just one more year! Why we plan on in 2017 because this is when he'll be finished his training for being a Police Officer and even though he gets paid for his training,he'll be put into a job after the last final interview if everything goes well so that would be June 2017! Would it be wrong to TTC even though we wouldn't be living together? I don't know if money should just be saved up so we can put a down payment on a house but we've been together for so long it just feels like waiting forever! The salary for the first year is 54,000$ then after a year there's a couple thousand dollar raise. Money wouldn't be a issue and I'll be starting college then also.. I'm not planning on being a SAHM but I know that I'll have to go back to school after the baby is born. BUT you'll never know if we'll conceive right away! I just need opinions because I don't know what's right and wrong. Yes I live at home but trust me my Mom would be so excited. She always smiles and says that I'll be the first one pregnant out of my 4 sisters and that's 'all we can do' I'm old enough to make my own decisions I know but just need some advice :) thanks ladies!!❤️
