I don't think I'm ever going to move on from this

I lost my baby boy when I was 4 months pregnant last year. I was watching a show and a married couple were doing an ultrasound at 12 weeks and it just remind me of my baby boy. I've been crying all day.I'm going to be 20 years old,I'm not financially stable to have a baby and I've been preventing that... but deep down I want to be pregnant again.
