Did i make the right choice..

I'm 17 weeks and sometimes all I can think about is if I made the right choice in keeping my baby..I really thought about termination but all that made me think about was if it'd be a boy or a girl or would they be athletic or smart or artistic and that sort of stuff and I couldn't find the ability to get over the fact that I would never get to know. But there was always the side of me and my SO not being financially stable and me just starting university in September and it just not being remotely a good time for a baby and it makes me worry that I made the wrong choice by having her..
