Trying for my second

I’m 21 years old and my fiancé will be 23 next month. Our first child is four years old, I had her at 17. I didn’t get to enjoy my first pregnancy at all back then and nothing happened the way most first time pregnancy’s happen, due to a small sh***y support system and horrible stress and neglect...now I have a different man in my life for 3.5 years and a better support system and a happier life with my own house/car ex....could my second pregnancy be more fulfilling or will I still feel like I’ve already been there and done that.... ?
