advice on a baby in college

Hi im 21 turning 22 and engaged to be married in August. Me and my fiancé have been together 5 years and look forward to starting a family right after the wedding but i was wondering how hard it will be or not hard. We have our own place we stay an hour away from family because of my school i work part time and graduate summer 2018 he works full time and graduates this April. This is something I wouldn't talk to my family about theyd think im crazy his family on the other hand cant wait until we have a baby either.
